Question

Sample A is a hard crystalline solid, which does not break easily.
Sample B is a solid that readily dissolves in water.
Sample C is a liquid that evaporates at room temperature.
Sample D is a colored liquid that conducts electricity.

Which sample is a covalent compound?

Answer 1

Answer: Sample C is a covalent compound.

Explanation:

A covalent compound is a compound formed by the sharing of electrons.

Properties of a covalent compound are as follows.

• They have low melting and boiling point as they have weak intermolecular forces which can be easily broken down at low temperature.
• Covalent compounds do not conduct electricity.
• Covalent compounds do not dissolve easily.
• Due to weak intermolecular forces, a covalent compound can be easily broken down as compared to an ionic compound.

Out of the give samples, only sample C represents property of a covalent compound as Sample C is a liquid that evaporates at room temperature.

Thus, we can conclude that sample C is a covalent compound.
