- #10What
role does the molecular interaction play in a solution of alcohol and
water?Ans : In pure alcohol and
water, the molecules are held tightly by a strong hydrogen bonding.
The interaction between the molecules of alcohol and water is weaker
than alcohol-alcohol and water-water interactions. As a
result, when alcohol and water are mixed, the intermolecular
interactions become weaker and the molecules can easily escape. This
increases the vapour pressure of the solution, which in turn lowers
the boiling point of the resulting solution.
