(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)` is unstable due to pressence of unparied electron or odd number of valence electrons, therefore, it forms dimer `N_(2)O_(4)` Which has even number of electrons and is stable.
