Azeotropic mixtures are

Rectified spirit obtained by fermentation contains $4.5 \%$ of water. To remove this water,rectified spirit is mixed with a suitable quantity of benzene and heated. Benzene helps because:

An azeotropic solution of two liquids is one that:

Given below are two statements:
Statement $(I)$: $1,2,3$-Trihydroxypropane can be separated from water by simple distillation.
Statement $(II)$: An azeotropic mixture cannot be separated by fractional distillation.

Absolute alcohol cannot be prepared by fractional distillation of rectified spirit since:

When do azeotropic mixtures of two liquids boil at a temperature lower than their boiling points?
