The species in which the N-atom is in a state of sp hybridisation is

Options

A. `NO_2^(-)`
B. `NO_3^(-)`
C. `NO_2`
D. `NO_2^(+)`

Answer

D

Explanation

(a) `NO_2^(-)`
`H=1/2(V+M-C+A)`
`H=1/2(5+0-0+1)=3`
`sp^2` hybridization with 1 lone pair and bent shape.

(b) `NO_3^(-)`
`H=1/2(5+0-0+1)=3`
`rArrsp^2` hybridization and trigonal planar structure.

(c) `NO_2`
Nitrogen show special type of bonding where it is sp2 - hybridized and bent shape.
(d) `NO_2^(+)`
`H=1/2(5+0-1+0)=2`

`rArr` sp hybridization.
