Question

A compound with low boiling point is ______.

Options

• Sodium chloride

• Calcium chloride

• Potassium chloride

• Carbon tetrachloride

Answer 1

A compound with low boiling point is carbon tetrachloride.

Explanation:

Sodium chloride, potassium chloride, and calcium chloride are ionic compounds held together by exceptionally strong electrostatic forces of attraction, resulting in very high boiling points. In contrast, carbon tetrachloride (CCl₄) is a covalent compound made of neutral molecules bound only by weak intermolecular Van der Waals forces. Because these weak forces require minimal thermal energy to break, carbon tetrachloride has a much low boiling point and exists as a volatile liquid at room temperature.
