Question 10 What are oxidizing agents? Solution: Oxidizing agents are the substances that gain electrons in an redox reaction and whose oxidation number is reduced. Question 11 Explain the nature of the covalent bond using the bond formation of CH 3 Cl. Solution: CH 3 Cl methyl chloride is made up of one carbon atom, three hydrogen atoms and one chlorine atom. Carbon atom has 4 valence electrons, each hydrogen atom has one valence electron, and a chlorine atom has 7 valence electrons.
Carbon atom shares its four valence electrons with three hydrogen atoms and 1 chlorine atom to form methyl chloride as follows: From the above reaction, in the dot structure of methyl chloride CH 3 Cl there are Class 10th Science Chapter 4 Ncert Solutions English Class 10th Science Chapter 4 Ncert Solutions English four pairs of shared electrons between carbon and other atoms. Each pair of shared electrons constitutes one single covalent bond. So, methyl chloride has four single covalent bonds.
Question 12 Draw the Class Solutions 4 10th Science Ncert English Chapter Class 10th Science Chapter 4 Ncert Solutions English electron dot structures for- Solution:. Question 13 What is a homologous series? Solution: Homologous series is a series of compounds with a similar general formula, possessing similar chemical properties due to the presence of the same functional group, and shows a gradation in physical properties as a result of increase in molecular size and mass.
For example, methane has a lower boiling point than Ncert Class Science English Chapter Solutions 4 10th Class 10th Science Chapter 4 Ncert Solutions English 10th Class English 4 Science Chapter Ncert Solutions ethane since it has more intermolecular forces with neighbouring molecules. This is because of the increase in the number of atoms making up the molecule. Question 14 How can ethanol and Ethanoic Class 10th Science Chapter 4 Ncert Solutions English Solutions 4 Class 10th Science Chapter English Ncert acid be differentiated on the basis of their physical and chemical properties? Solution: i Ethanol has a pleasant smell whereas ethanoic acid has the smell of vinegar. Question 15 Why does micelle 4 English Ncert Science Chapter 10th Solutions Class formation take place when soap is added to water?
Will a micelle be formed in other solvents such as ethanol also? Solution: Micelle formation takes place when soap is added to water. This is because when soap is added to water in which dirty clothes are soaked, the two parts of the soap molecule dissolves in two different mediums.
The organic tail dissolves in Class 10th Science Chapter 4 Ncert Solutions English Class 10th Science Chapter 4 Ncert Solutions English the dirt, grime or grease and the ionic head dissolves in water. When the clothes are rinsed or agitated, the dirt gets pulled out of the clothes in the water by the Class 10th Science Chapter 4 Ncert Solutions English soap molecule. In this way the soap does its cleaning work on dirty and grimy clothes or hands. The soap molecules actually form a closed structure because of mutual repulsion of the Class 10th Science Chapter 4 Ncert Solutions English positively charged heads.
This structure is called a micelle. Question 16 Why are carbon and its compounds used as fuels for most applications? Solution: Carbon and its compounds are used as fuels Class 10th Science Chapter 4 Ncert Solutions English for most of the applications because they burn in air releasing a lot of heat energy.
Question 17 Explain the formation of scum when hard water is treated with soap. Solution: The Class 10th Science Chapter 4 Ncert Solutions English precipitate form of scum is formed when soap is used for washing clothes. With hard water, a large amount of soap is wasted in reacting with the calcium and magnesium ions of hard water to form an insoluble precipitate.
The precipitate form formed by the action of hard water on soap, sticks to the clothes being washed and interferes with the cleaning ability of Class 10th Science Chapter 4 Ncert Solutions English the additional soap. This makes the cleaning of clothes difficult. Question 18 What change will you observe if you test soap with litmus paper red and blue?
Solution: Soap is the salt of a strong base NaOH and a weak acid carboxylic acid , so a solution of soap in water is basic in nature. Being basic, a soap solution turns red litmus paper blue. Question Science English Chapter Class 10th Solutions Ncert 4 19 What is hydrogenation? Solution: It is a class of chemical reactions in which the net result is addition of hydrogen H 2 to unsaturated organic compounds such as alkenes, alkynes, etc. Hydrogenation is widely applied to the processing of vegetable oils and fats.
Complete hydrogenation converts unsaturated fatty acids to saturated ones. From the above hydrocarbons C 2 H 2 is an Chapter English Science 4 Solutions Class Ncert 10th Class 10th Science Chapter 4 Ncert Solutions English Class 10th Science Chapter 4 Ncert Solutions English alkyne, whereas C 3 H 6 is an alkene. So, C 3 H 6 and C 2 H 2 will undergo addition reactions. Question 21 Give a test that can be used English Class Chapter Science 4 10th Ncert Solutions Class 10th Science Chapter 4 Ncert Solutions English to differentiate chemically between butter and cooking oil.
Solution: Bromine water test can be used to differentiate chemically between butter and cooking oil. Add bromine water to a little of cooking oil Class 10th Science Chapter 4 Ncert Solutions English Class Chapter 4 Science Solutions Ncert English 10th and butter taken in separate test tubes. Decolourising of bromine water by cooking oil unsaturated compound b. Butter saturated compound does not decolourise bromine water. Question 22 Explain the mechanism of the cleaning action of soaps. Solution: We all know that soap is used to remove dirt and and grime from substances.
Generally dirt and grime get stuck because they have an oily component, Class 4 Chapter English Ncert Science Solutions 10th which is difficult to remove, by plain brushing or washing by water. A soap molecule has two parts, a head and a tail i. A soap molecule has a tadpole like Class 10th Science Chapter 4 Ncert Solutions English Class 10th Science Chapter 4 Ncert Solutions English Science Chapter Ncert Class English 4 10th Solutions structure shown below. The organic part is water insoluble but is soluble in organic solvents or in oil or grease. The ionic part is soluble in water, as water is a polar solvent. When soap is added to water in which dirty clothes are soaked, the two parts of the soap molecule dissolve in two different mediums.
When the clothes are rinsed or agitated, Class 10th Science Chapter 4 Ncert Solutions English the dirt gets pulled out of the clothes, by the soap molecule. In this way soap does its cleaning work on dirty and grimy clothes or hands. The micelle pulls out the dirt and grime more efficiently.
Question 23 Would you be able to check if water is hard by using a detergent? Solution: We would not be able to check whether a sample Ncert Science Class Chapter Solutions 4 10th English of water is hard by using a detergent, this is because a detergent forms lather easily even with hard water. Question 24 People use a variety of methods to wash clothes. Solution: 4 Chapter Ncert Science Class Solutions English 10th Class 10th Science Chapter 4 Ncert Solutions English It is necessary to shake to get clean clothes because the soap micelles, which entrap oily or greasy particles on the surface of dirty clothes, have to be removed from their surface.
When the clothes which are wet by soap solution are beaten, the micelles containing oil or greasy dirt particles get removed from the surface of dirty clothes and go into water and the dirty cloth gets cleaned.

Answer: d All esters have the common structure of Ncert Solutions For Class 10th Science Chapter 7 Key carboxylic group represented Class 10th Science Chapter 4 Ncert Solutions English by the suffix date. Carbon is an important constituent of the foods, fuels, household and commercial articles, textile fabrics, perfumes, explosives, dyes, war gases etc. Allotropes of Carbon An element, in different forms, having different physical properties but similar chemical properties is known as allotropes of that element.
Carbon has three well known allotropes which are graphite, diamond and buck minster fullerene. Fullerene: This is another class of carbon allotropes. The first one to be identified was C which has carbon atoms arranged in the shape of a football. Since this looked like the geodesic dome designed by the US architect Buckminster Fuller, the molecule was named fullerene. Unsaturated hydrocarbons: Compounds consist of a single, double or triple bond between carbon-carbon atoms.
Cycloalkanes: These hydrocarbons possess one or multiple carbon rings. The hydrogen atom is attached to the carbon ring. Aromatic hydrocarbons: These are also called as arenes.
Arenes are compounds which consist of at least one aromatic ring. Soaps: Ester of higher fatty acids is called soap. It is manufactured by the reaction of caster of higher fatty acid with sodium hydroxide. The sodium salt so formed has cleansing property. Detergents: Soap cannot form lather in hard water. To overcome this problem, detergents were introduced. Detergent is also known as soapless soap. Detergent is sodium salt of benzene sulphonic acid or sodium Class 10th Science Chapter 4 Ncert Solutions English Class 10th Science Chapter 4 Ncert Solutions English salt of long chain alkyl hydrogen sulphate.
Oxidation Reactions: Though combustion is generally an oxidation reaction, not all oxidation reactions are combustion reactions. Oxidation is also carried out by using oxidizing agents Oxidants.
Addition reactions: Unsaturated organic compounds, like alkenes and alkynes, undergo addition reactions to become saturated in nature. Substitution reactions are single displacement reactions.
