Question

Draw the structure of ammonia and give the reason for alkaline nature of aqueous ammonia.

Answer 1

The presence of lone pair of electrons on the nitrogen atom makes ammonia basic in nature in its aqueous solution . Aqueous solution of ammonia dissociates partially to produce hydroxylion.

\[\ce{Nh3 + H2O ⇌ NH4OH}\]

\[\ce{NH4OH ⇌ NH+4 + OH-}\]

Key: Aqueous solution of ammonia is alkaline in nature.
