Assertion (A): ${NO}_3^{-}$ is planar while ${NH}_3$ is pyramidal. Reason (R): ${N}$ in ${NO}_3^{-}$ is ${sp}^2$ hybridized but in ${NH}_3$ it is ${sp}^3$-hybridized.

Both (A) and (R) are true but (R) is not the correct explanation of (A)

Correct option: A

Both (A) and (R) are true and (R) is the correct explanation of (A)

Option A (Both (A) and (R) are true and (R) is the correct explanation of (A)) is correct because the planar structure of NO

{}_3^{-}

is due to sp

{}^2

hybridization, while the pyramidal structure of NH

{}_3

is due to sp

{}^3

hybridization.
