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

Answer

3

Explanation

`|{:("Species","Steric Number","Hybridization"),(BF_(3),3+0,sp^(2)),(NO_(2)^(-),2+1,sp^(2)),(NH_(2)^(-),2+2,sp^(3)),(H_(2)O,2+2,sp^(3)):}|`
