An aqueous solution of methanol in water has vapour pressure

Question

An aqueous solution of methanol in water has vapour pressure (A) less than that of water (B) more than that of water (C) equal to that of water (D) eqdal to that of methanol

Tardigrade Admin · Accepted Answer

The vapour pressure of an aqueous methanol solution is more than that of water but less than that of methanol. This is due to solute-solvent interaction is more due to the formation of hydrogen bonding than methanol but less than water.
