In which of the following molecular/ions `BF_(2),NO_(2)^(-),NH_(2)` and ` H_(2)O` the correct atom is `sp^(2)` hybridized ?

Options

A. `BF_(3) and NO_(2)^(-)`
B. ` NO_(2)^(-) and NH_(2)^(-)`
C. `NH_(2)^(-) and H_(2)O`
D. `NO_(2)^(-) and H_(2)O`

Answer

a

Explanation

`{:("Molecule","hybridisation"),(BF_(3),sp^(2)),(NO_(2)^(-),sp^(2)),(NH_(2)^(-),sp^(3)),(H_(2)O,sp^(3)):}`
`rArr BF_(3)` and ,`NO_(2)^(-)` are ,`sp^(2)`hybridized.
Hence,option (a) is correct.
