Q22 / 160 · AP EAMCET 2023 (18 May Shift 2) · Chemistry

At $298 \mathrm{~K}$, if the vapour pressure of pure liquids toluene, benzene, chloroform and dichloromethane are 60,160, 200 and 415 torr respectively. Then which liquid is having high boiling point?

Correct answer
A
Toluene
B
Benzene
C
Chloroform
D
Dichloromethane

Solution

The vapour pressure will be lowest for least volatile liquid for which the boiling point will be highest. Since toluene has the lowest vapour pressure, its boiling point will be highest.

Hence, the correct answer is option: 'A'.
