In which of the following molecules/ions in the central atom `sp^2`-hybridized?

A

`NO_2^(-) and NH_2^(-)`

B

`NH_2^(-) and H_2O`

C

`NO_2^(-) and H_2O`

D

`BF_3 and NO_2^(-)`

Text Solution

Verified by Experts

The correct Answer is:
D
In `BF_3`
`H = 1/2 (V + M - C+A)`
`H = 1/2 (3 + 3 - 0 + 0) = 3 rArr sp^2` hybridization.
In `NO_2^(-)`
`H = 1/2 (5 + 0 - 0 + 1) = 3 rArr sp^2` hybridization.
