Class 10 Science Chapter 4 MCQ : Carbon and its Compounds MCQs Quiz
Chapter 4, Carbon and its Compounds, explores the versatile nature of carbon and its ability to form a vast number of compounds due to properties like catenation and tetravalency. The chapter begins by explaining covalent bonding, distinguishing it from ionic bonding. It classifies hydrocarbons into saturated (alkanes) and unsaturated (alkenes and alkynes) based on the types of bonds. Students learn about the IUPAC names, chemical properties of different functional groups (alcohol, aldehydes, ketones, carboxylic acids), and the importance of homologous series. Additionally, the chapter covers crucial topics such as the combustion, oxidation, and addition reactions of carbon compounds, concluding with an explanation of soaps and detergents and their cleansing action (micelles formation).
Conclusion
Scoring high in Class 10 Science requires a solid understanding of organic chemistry fundamentals. By completing this Carbon and its Compounds Class 10 MCQs Quiz, you have tested your grasp on complex concepts like isomerism, functional groups, and chemical reactions of carbon. Regular practice of these Class 10 Science Chapter 4 Quiz questions will significantly improve your recall speed and accuracy for the board examination.

FAQs on Class 10 Science Chapter 4 MCQ : Carbon and its Compounds
- Why does carbon form covalent bonds?
Carbon forms covalent bonds because it cannot lose or gain four electrons to complete its octet due to high energy requirements; instead, it shares electrons with other atoms. - What is catenation?
Catenation is the ability of carbon atoms to bond with other carbon atoms, forming long chains, branched chains, or rings. - What is the difference between a soap and a detergent?
Soaps are sodium or potassium salts of long-chain fatty acids that work well in soft water, while detergents are generally ammonium or sulfonate salts of long-chain hydrocarbons that work effectively in hard water. - Name the functional group present in ethanol.
The functional group present in ethanol is the hydroxyl group (-OH). - What happens when ethanol is heated with excess concentrated sulphuric acid?
When ethanol is heated with excess concentrated sulphuric acid at 443 K, it undergoes dehydration to form ethene. - Define the term ‘homologous series’.
A homologous series is a series of organic compounds having the same functional group, similar chemical properties, and successive members differing by a $-CH_2-$ unit. - What are hydrocarbons?
Hydrocarbons are compounds containing only carbon and hydrogen elements. - What is a functional group?
A functional group is an atom or a group of atoms in a molecule that determines its chemical properties and the nature of the reaction it undergoes. - Give an example of a saturated hydrocarbon.
Methane ($CH_4$) is an example of a saturated hydrocarbon. - Why is ethanoic acid called glacial acetic acid?
Pure ethanoic acid (100%) freezes at around 290 K (16.6°C) to form a glacial mass, which is why it is often called glacial acetic acid.
