Question

In which of the following pairs of molecules/ions, the central atoms have ${sp}^2$ hybridisation?

• A. $B{F}_3$ and $N{H}_2^{-}$
• B. $N{O}_2^{-}$ and $N{H}_3$
• C. $B{F}_3$ and $N{O}_2^{-}$
• D. $N{H}_2^{-}$ and $H_{2}O$

Answer 1

The correct option is C $B{F}_3$ and $N{O}_2^{-}$

$B{F}_3$ and $N{O}_2^{-}$ are ${sp}^2$ hybridised while $N{H}_2^{-},N{H}_3$ and $H_{2}O$ are ${sp}^3$ hybridised.

Hence option (C) is correct.
