Question

Which of the following are molecular solids and which are covalent solids? SO2, I2, P4, S8, H2O, SiO2

Answer 1

Answer;

1) Moleculer solids; I2, S8 and P4 2) Covalent solids; SiO2; 3) Moleculer liquid; H2O 4) Moleculer gas; SO2

Explanation:

In Moleculer compounds the molecules are held together by intermoleculer forces such as van der waals forces and dipole-dipole interaction. They have weak melting and boiling point.

Covelent compounds are held together by covalent bond. They have strong melting and boiling point.
