    Carbon and Its Compounds Class 10 Solutions of Practice Questions

    Carbon and Its Compounds Class 10 Solutions

    Ans 1. (i) CH3Cl Chloromethane
    (ii) C2H5Cl Chloroethane

    Ans 2. Covalent compounds have low melting and boiling points due to small intermolecular forces of attraction between the atoms.

    Ans 3. (i) Alcohol group
    (ii) Carboxylic acid group

    Ans 4. Unsaturated hydrocarbons have more amount of carbon, therefore burn with smoky flame due to incomplete combustion.

    Ans 5. (i) Valency of each carbon atom in an alkane is four.
    (ii) Valency of each carbon atom in an alkyne is four.

    Ans 6. (i) Catenation
    (ii) Tetravalency of carbon

    Ans 7. Soap reacts with Ca2+ and Mg2+ ions present in hard water to form scum.

    Ans 8. In the structure of a diamond, all four valence electrons of carbon are involved in the formation of covalent bonds. Thus, no free electrons are available. Whereas, in the structure of graphite, three electrons in the valence shell of carbon are involved in covalent bond formation and the fourth electron is free to move. Therefore, graphite is a good conductor of electricity.

    Ans 9. (a) Carbon forms a large number of compounds since carbon is small in size and can form stable covalent bonds (catenation) and it shows tetravalency.

    (b) Air holes of the gas burner are made open (adjusted) so that air can pass through, which is needed for complete combustion so that heated vessels do not get blackened.

    Ans 10. The purple color of KMnO4 decolorises and ethanoic acid will be formed
    C2H5OH ——Alk KMnO4 —–àCH2 COOH

    Ans 11. (b) Ni

    Ans 12. (a) only single bonds

    Ans 13. (b) CH4

    Ans 14. (d) Lamp black

    Ans 15. (b) Ethane

    Ans 16. (d) LPG

    Ans 17. (c) They all contain double bond

    Ans 18. (a) Addition reaction

    Ans 19. (c) Graphite is a bad conductor of heat and electricity.

    Ans 20. (c) Carbon dioxide and water

    Ans 21. (a) Glycerol

    Ans 22. (a) 14 a.m.u and CH2 respectively

    Ans 23. (d) CCl4

    Ans 24. (b) Molecular formula

    Ans 25. (b) Unsaturated, as sooty deposit represents unburnt hydrocarbons

    Ans 26. (d) Sugar-ethanol

    Ans 27. (b) Cyclohexane

    Ans 28. (b) carbon monoxide in traces and carbon dioxide.

    Ans 29. (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

    Ans 30. (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

    Ans 31. (d) Assertion (A) is false but reason (R) is true. Carbon compounds are mainly poor conductors of electricity.

    Ans 32. (d) Assertion (A) is false but reason (R) is true.

    Ans 33. (d) Assertion (A) is false but reason (R) is true.

    Ans 34. (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

    Ans 35. (b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
