The given graph shows the vapour pressure- temperature curves for some liquids.
Liquid 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
Answer
Diethyl ether, acetone, ethyl alcohol, water
Explanation
Solution
The vapour pressure increase with increase in
intermolecular forces. When the forces are weak, the liquid has high volatility and maximum vapour pressure diethyl ether has higher vapoour pressure while water has lowest vapour pressure.
