Chemical Bonding and Molecular Structure - Result Question 56
####57. In which of the following pairs of molecules/ ions, the central atoms have $s p^{2}$ hybridization?
(a) $NO_2^{-}$and $NH_3$
(b) $BF_3$ and $NO_2^{-}$
(c) $NH_2^{-}$and $H_2 O$
(d) $BF_3$ and $NH_2^{-}$
Show Answer
Solution:
$ \begin{aligned} & \text{ (b) } BF_3: \frac{3+3}{2}=3 \text{ means } s p^{2} \text{ hybridisation } \\ & NO_2^{-}: \frac{5+1}{2}=3 \text{ means } s p^{2} \text{ hybridisation } \end{aligned} $
