Question: Explain the formation of scum when hard water is treated with soap. Answer: Soap does not work properly when the water is hard. Soap molecules are long carbon chains with sodium or potassium ions at the other end. When soap is added to hard water, calcium and magnesium ions present in hard water displace sodium or potassium ions from the soap molecules forming an insoluble substance called scum. A lot of soap gets wasted in the process of scum formation.
Question: What change will you observe if you test soap with litmus paper (red and blue)? Answer: Usually, litmus paper is either red or blue. Litmus paper is an indicator that turns blue from red in basic conditions and vice versa in acidic conditions. Since soap is basic in nature, it will turn red litmus to blue. Whereas, no change in the colour of blue litmus paper takes place when it is tested with soap.
Question: Which of the following hydrocarbons undergo addition reactions: C2H6, C3H8, C3H6, C2H2 and CH4? Answer: Saturated hydrocarbons (alkane, general formula CnH2n+2) undergo substitution reactions and not addition reactions. Hence, C2H6, C3H8 and CH4 do not undergo addition reactions because these molecules already have a maximum number of hydrogen atoms they can accommodate. Unsaturated hydrocarbons (alkenes CnH2n and alkynes CnH2n-2) undergo addition reactions. C3H6 and C2H2, being unsaturated hydrocarbons, the double and triple bonds can be converted to single bonds and thus, such compounds undergo additional reactions.
Class 10 Science Chapter 4 In-text Questions
Below we have provided the in-text questions for CBSE Class 10 Science Chapter 4. These questions from will help you gain a conceptual understanding of all the concepts.
1. What would be the electron dot structure of carbon dioxide that has the formula CO2? 2. What would be the electron dot structure of a molecule of Sulphur that is made up of eight atoms of Sulphur? 3. How many structural isomers can you draw for pentane? 4. What are the two properties of carbon that lead to the huge number of carbon compounds we see around us? 5. What will be the formula and electron dot structure of cyclopentane? 6. Draw the structures for the following compounds. (i) Ethanoic acid (ii) Bromopentane (iii) Butanone (iv) Hexanal *Are structural isomers possible for Bromopentane? 7. How would you name the following compounds? 8. Why is the conversion of ethanol to ethanoic acid an oxidation reaction? 9. A mixture of oxygen and ethyne is burnt for welding. Can you tell why a mixture of ethyne and air is not used? 10. How would you distinguish experimentally between alcohol and carboxylic acid? 11. What are oxidizing agents? 12. Would you be able to check if water is hard by using a detergent? 13. People use a variety of methods to wash clothes. Usually after adding the soap, they ‘beat’ the clothes on a stone, or beat it with a paddle, scrub with a brush, or the mixture is agitated in a washing machine. Why is agitation necessary to get clean clothes?

In this chapter, students will get introduced to Carbon and its characteristics. This includes its covalent nature and versatility: how it forms millions of saturated and unsaturated compounds structured in chains, branches, or rings. Through NCERT Class 10 Chapter 4, students will understand the importance of Carbon as the basis for all living organisms and many things we use. Students will also learn how these compounds are named based on the functional groups they are attached to.
‘TheCarbon and its Compounds’ chapter also provide insights intoisomers, alkanes, alkenes, alkynes, allotropes of Carbon, and fundamentals of homologous series. The chapter covers the four main chemical reactions: combustion, oxidation, addition, and substitution. Additionally, students will learn about the properties of Ethanol and Ethanoic acid and the chemical properties of soaps and detergents.
FAQs on NCERT Class 10 Science Solutions Chapter 4
Q1. What are the exercises in NCERT Solutions for Class 10 Science Chapter 4? Ans. There are 4 exercises in Carbon And Its Compounds: Ex 4.1: Bonding In Carbon – The Covalent Bond Ex 4.2: Chemical Properties Of Carbon Compounds Ex 4.3: Some Important Carbon Compounds – Ethanol And Ethanoic Acid Ex 4.4: Soaps And Detergents
Q2. Name any four chemical properties of Carbon. Ans. The chemical properties of Carbon are as follows: Chemical Formula: C. Oxidation: Combines with oxygen to produce carbon dioxide (CO2 ) and carbon monoxide (CO). Reactivity: Carbon does not dissolve in or react with water or acids. Chains of atoms: Carbon can make long strings, or chains, of atoms.
Q3. What are soaps and detergents Class 10? Ans. Soap is a sodium salt or potassium salt of long-chain fatty acids having cleansing action in the water. They are used as cleansing agents to remove dirt and oil from the skin and clothes. Detergents have almost the same properties as soaps but are more effective in hard water.
Q4. What are micelles? Ans. Micelles are lipid molecules that arrange themselves in a spherical form in aqueous solutions. The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic regions (polar head groups) and hydrophobic regions (the long hydrophobic chain).
Q5. What are the types of Covalent Bond Class 10? Ans. Covalent bonds can be single, double, and triple bonds. Single bonds occur when two electrons are shared and are composed of one sigma bond between the two atoms. Double bonds occur when four electrons are shared between the two atoms and consist of one sigma bond and one pi bond.
