Pick out the incorrect statement

Options

A. Nitrogen dioxide has odd number of electrons and its structure is linear and has N-O bonds of different lengths
B. `NO_2` in paramagnetic
C. `N_2O_4` has planar structure and all N-O bonds are equivalent and is also diamagnetic molecule containing an
D. `N_2O_4` ionizes slightly to form `NO^(+) and NO_(3)^(-)` ions.

Answer

A

Explanation

`NO_(2)` has angular structure and has all N-O bonds equivalent, because of resonance.
It has both covalent and coordinate bonds.
It has both covalent and coordinate bonds.
(b) Since `NO_(2)` has an unpaired electron, so it is paramagnetic.
(c) The old electron on each of hte nitrogen atoms of `NO_(2)` molecules are unpaired up to form a weak N-N bond. The molecule is a resonance hybrid, since all N-O are equivalent.

(d) `N_(2)O_(4) Leftrightarrow NO^(+)+NO_(3)^(-)`
