In which of the following set of molecules central atoms are `sp^(3)` hybridised ?

Options

A. `PCl_(3),BCl_(3),NCl_(3)`
B. `SnCl_(2),I_(3)^(+),I_(3)^(-)`
C. `NH_(2)^(-),PCl_(3),CH_(3)^(-)`
D. `NH_(4)^(+),BF_(4)^(+),SF_(4)`

Answer

C

Explanation

`{:(PCl_(3),BCl_(3),NCl_(3),SnCl_(2),I_(3)^(o+),I_(3)^(Theta),NH_(2)^(-),CH_(3)^(-),NH_(4)^(+),SF_(4)),(sp^(3),sp^(2),sp^(3),sp^(2),sp^(3),sp^(3)d,sp^(3),sp^(3),sp^(3),sp^(3)d):}`
