The boiling point of an azeotropic mixture of water and ethyl alcohol is less than that of the theoretical value of water and alcohol mixture. Hence the mixture shows

Options

A. The solution is highly saturated.
B. Positive deviation from Raoult's law.
C. Negative deviation from Raoult's law.
D. Nothing can be said.

Answer

B

Explanation

Positive deviation from Raoult's law are noticed when
Experimental value of vapour pressure of mixture is more than calculated value.
Experimental value of boiling point of mixture is less than the calculated value.
`Delta_("mixing")H = +ve`
`Delta_("mixing")V = +ve`
