Ethyl alcohol, CH;CH2OH Water, H20 Diethyl ether, CH3CH2OCH CHs Bromine, Br2Explanation / Answer
Ethyl alcohol - Hydrogen bonding
Water - Hydrogen bonding
Diethyl ether - London dispersion forces
Bromine - London dispersion forces
Vapour pressure increasing order
Water < Ethyl alcohol < Bromine < Diethyl ether
