Text Solution

Verified by Experts

The correct Answer is:
A
Azeotropic distillation method
rectified sprit `+ underset(darr"Fractional distillation")"Benzene"+water`
First fraction at `331.8K` is ternary azetrope `(H_(2)O7.4%+` Benzene `74% +` alcohol `18.5%)`
Second fraction `341.2K` is a binary azeotrope (Benzene `67.7%+` Alcohol `32.2%`)
Last fraction at `351K` is absolute alcohol.
