Question

At a given temperature which of the following liquids has highest vapour pressure? (A) Ether (B) Water (C) Glycol (D) Glycerol

Tardigrade Admin · Accepted Answer

Ether has the highest vapour pressure (i.e., lowest boilint point) at any temperature. The reason for its high vapour pressure is that the attraction is less between ether molecules than between water and alcohol molecules.
