Q23 / 90 · JEE Main 2021 (27 Aug Shift 2) · Chemistry

The number of species having non-pyramidal shape among the following is:
$(A) {SO}_{3}$
$(B) {NO}_{3}^{-}$
$(C) {PCl}_{3}$
$(D) {CO}_{3}^{2 -}$

Correct answer: 3

Solution

Hence non-pyramidal species are ${SO}_{3}, {NO}_{3}^{-}$ and ${CO}_{3}^{2 -}$ .

Hence, the correct answer is 3.
