List of top Chemistry Questions on Azeotropes and eutectics asked in CBSE CLASS XII

The boiling point of an azeotropic mixture of water and ethanol is less than that of pure water and ethanol. The mixture shows:

Assertion (A): Components of azeotropes are easily separated by fractional distillation.
Reason (R): Components of an azeotrope have same composition in liquid and vapour phase.

Assertion (A): \( p \)-nitroaniline is a weaker base than \( p \)-toluidine.
Reason (R): The electron-donating \( -NO_2 \) group in \( p \)-nitroaniline makes it a weaker base.
