Question

What are molecular compounds usually composed of?

Answer 1

Molecular compound consists of individual molecules that contain only covalent bonds. For example, CH4, CO2, C6H6 etc.

Explanation:

Molecular compound consists of individual molecules that contain only covalent bonds.
The covalent bonds within the molecules are very strong and highly directional, so the molecules usually have definite shapes and retain their identities during physical changes.
The forces between the molecules are by comparison very weak. It's these weak intermolecular forces that determine many of the properties of covalent molecular compounds.
