Ammonia and Nitric acid are two industrially important compounds. Account for the following: `NO_2` undergoes dimerisation.

Text Solution

Verified by Experts

`NO_2` is an odd electron molecule. Odd electrons present on two nitrogen atoms form covalent bond on dimerisation.. Thus it is converted to stable `N_2O_4` with even number of electrons.
