Question

State True or False.

A liquid having high vapor pressure has low boiling point.

• A. True
• B. False

Answer 1

The correct option is A True

Liquids boil when their vapour pressure becomes equal to the external pressure. If a liquid has a high vapour pressure at some temperature, you won't have to increase the temperature very much until the vapour pressure reaches the external pressure. Hence the liquid with the higher vapour pressure at a particular temperature is the one with the lower boiling point.
