The given graph shows the vapour pressure - temperature curves for some liquids

Liquids A,B, C and D respectively are

A

diethyl ether, acetone , ethyl alcohol , water

B

acetone , ethyl alcohol, diethyl ether , water

C

water, ethyl alcohol , acetone , diethyl ether

D

ethyl alcohol, acetone , diethyl ether, water

Text Solution

Verified by Experts

The correct Answer is:
A
The vapour pressure increases with decrease in intermolecular forces . When the forces are weak, the liquid has high volatility and maximum vapour pressure . Diethyl ether has highest vapour pressure while water has lowest vapour pressure.
