Q. Which of the following sequence of $T$ and $F$ is correct for given statements. Here $T$ stands for true statement and $F$ stands for false statement?
(i) Ionic solids are electrical insulators in the solid state but conduct electricity in molten state.
(ii) Graphite is a covalent solid.
(iii) Covalent solids are conductor of electricity.
(iv) Non polar molecular solids are held by weak dispersion forces or London forces while polar molecular solids are held by stronger dipole - dipole interactions.

The Solid State

Solution:

Covalent solids are insulator of electricity. Graphite is a covalent solid but it is a conductor of electricity due to its structure.
