Q. 4. B. Explain the terms with an example. 
 
Covalent bond 
Answer : The chemical bond formed by sharing of two valence electrons between the 
two atoms is called the covalent bond. Examples:- H2 
 
Q. 4. C. Explain the terms with an example. 
 
Hetero atom in a carbon compound 
Answer : The atoms of the elements such as halogen, oxygen, nitrogen substitute one 
or more hydrogen atoms in the hydrocarbon chain and thereby the tetra valency of 
carbon is satisfied. The atom of the element which is a substitute for hydrogen is 
referred as a hetero atom in carbon compounds. 
A heteroatom is any atom that is not carbon or hydrogen. Example: 
 
 
Note: Typical heteroatoms are nitrogen, oxygen, sulfur, phosphorus, chlorine, bromine, 
and iodine. 
Q. 4. D. Explain the terms with an example.

Functional group 
Answer : The compounds acquire specific chemical properties due to the hetero atoms 
or the groups. These hetero atoms or the groups containing hetero atoms are called 
functional groups. 
Examples: - alcohol (-OH), aldehyde ( – CHO) 
The major functional groups are shown below: 
 
Q. 4. E. Explain the terms with an example. 
 
Alkane 
Answer : The valencies of all the atoms are satisfied by the single bonds. Such 
compounds are called saturated compounds. Saturated hydrocarbons are called 
alkanes.

FAQs on Textbook Solutions: Carbon Compounds - Science and Technology Class 10 (Maharashtra SSC Board)

1. What are carbon compounds and why are they important in everyday life?
Ans. Carbon compounds, also known as organic compounds, are chemical compounds that contain carbon atoms. They are essential for life and are found in all living organisms. Carbon's unique ability to form four covalent bonds allows for the creation of a vast array of complex structures, including proteins, carbohydrates, lipids, and nucleic acids, which are vital for biological processes. Additionally, carbon compounds are used in various industries, including pharmaceuticals, plastics, and fuels, making them crucial for modern society.
2. What are the different types of carbon compounds?
Ans. Carbon compounds can be classified into several categories based on their structure and bonding. The main types include hydrocarbons (compounds composed only of carbon and hydrogen), functionalized hydrocarbons (which contain functional groups like alcohols, acids, and amines), and polymers (large molecules made up of repeating units). Hydrocarbons can further be divided into aliphatic (straight or branched chains) and aromatic (ring structures) compounds.
3. How do carbon compounds contribute to the greenhouse effect?
Ans. Carbon compounds, particularly carbon dioxide (CO2) and methane (CH4), are significant contributors to the greenhouse effect. These gases trap heat in the Earth's atmosphere, leading to global warming. Human activities, such as burning fossil fuels, deforestation, and industrial processes, have increased the concentration of these carbon compounds in the atmosphere, enhancing the natural greenhouse effect and resulting in climate change.
4. What are isomers and how are they related to carbon compounds?
Ans. Isomers are compounds that have the same molecular formula but different structural arrangements or configurations. In carbon compounds, isomerism is quite common due to the versatility of carbon bonding. Isomers can be classified into structural isomers (which differ in the connectivity of atoms) and stereoisomers (which differ in the spatial arrangement of atoms). Understanding isomerism is crucial in fields like pharmaceuticals, where different isomers can have different biological activities.
5. What role do carbon compounds play in organic chemistry?
Ans. Carbon compounds are the foundation of organic chemistry, which is the branch of chemistry that studies the structure, properties, and reactions of organic compounds. Organic chemistry focuses on the synthesis, reactivity, and behavior of carbon-containing compounds, making it essential for developing new materials, drugs, and biochemical processes. The study of carbon compounds enables scientists to understand and manipulate biological systems, leading to advancements in medicine, biotechnology, and environmental science.
