(a) Why does `NO_2` dimerise ?
(b) In what way can it be proved that `PH_3` is basic in nature ?

Text Solution

Verified by Experts

`NO_(2)` contains odd number of valence electrons. It behaves as a typical odd molecule. On dimerisation, it is converted to stable `N_(2)O_(4)` molecule with even number of electrons.
