are good conductors of electricity.
are poor conductors of electricity.
have strong forces of attraction between their molecules.
do not have strong forces of attraction between their molecules.

Options

A. (i) and (iii)
B. (ii) and (iii)
C. (i) and (iv)0
D. (ii) and (iv)

Answer

D

Explanation

The atomic number of carbon is 6 . So, its electron configuration is 2,4.Carbon having four valence electrons forms only covalent compounds which show less intermolecular attractions and do not have any free electrons to transmit electric current .Therefore ,these are poor conductors of electricity .Also ,the forces of attraction in between their molecules are weak.
