Which of the following statements are usually correct for carbon compounds? These
(i) are good conductors of electricity
(ii) are poor conductors of electricity
(iii) have strong forces of attraction between their molecules
(iv) do not have strong forces of attraction between their molecules
(a) (i) and (iii) (b) (ii) and (iii)
(c) (i) and (iv) (d) (ii) and (iv)
Answer:(d)
Solution:
Carbon predominantly forms covalent compounds, due to valency 4. Generally carbon is a poor conductor of electricity as its compounds are predominantly covalent in nature. The forces of attraction in between their molecules are weak as they are not covalent in nature.
Statement (ii) and (iv) are correct.
Therefore, option (d) is correct.
