FAQs on Solutions of Carbon And Its Compounds (Page No - 239) - Chemistry Lakhmir Singh, Class 10 - Extra Documents, Videos & Tests for Class 10

1. What are the different types of carbon compounds?
Ans. Carbon compounds can be broadly classified into three types: organic compounds, inorganic compounds, and organometallic compounds. Organic compounds are derived from living organisms and contain carbon atoms bonded to hydrogen atoms. Inorganic compounds are those that do not contain carbon atoms bonded to hydrogen, such as carbonates and carbides. Organometallic compounds are compounds that contain carbon atoms bonded to metal atoms.
2. What is the importance of carbon compounds in daily life?
Ans. Carbon compounds play a crucial role in our daily lives. They are the basis of life as all living organisms are made up of organic compounds. They are found in various forms such as carbohydrates, proteins, lipids, and nucleic acids. Carbon compounds are also used in industries for the production of fuels, plastics, pharmaceuticals, dyes, and many other useful substances.
3. How is carbon dioxide formed and what are its properties?
Ans. Carbon dioxide is formed through various natural and human activities. It is produced during respiration, combustion of fossil fuels, and decomposition of organic matter. Carbon dioxide is a colorless and odorless gas. It is denser than air and does not support combustion. It is soluble in water and forms carbonic acid. Excess carbon dioxide in the atmosphere contributes to the greenhouse effect and climate change.
4. What are hydrocarbons and their uses?
Ans. Hydrocarbons are organic compounds that consist only of carbon and hydrogen atoms. They can be classified into two types: saturated hydrocarbons (alkanes) and unsaturated hydrocarbons (alkenes and alkynes). Hydrocarbons are used as fuels, such as gasoline, diesel, and natural gas. They are also used as raw materials in the production of plastics, synthetic fibers, and many other industrial products.
5. How do carbon compounds exhibit catenation?
Ans. Catenation is the unique property of carbon atoms to form long chains or rings by bonding with other carbon atoms. Carbon compounds can form single, double, or triple bonds with other carbon atoms, giving rise to a variety of organic compounds. This property of carbon allows for the formation of complex and diverse molecules, making carbon the basis of organic chemistry.
