MCQ
Which one of the following species has plane triangular shape ?
- A$N_3$
- ✓$NO_{3}^-$
- C$NO_{2}^-$
- D$CO_2$
✓
Answer
Correct option: B.
$NO_{3}^-$
b
Species with $s p^{2}$ hybridisation are plane triangular in shape. Among the given species $N O_{3}^{-}$ is $s p^{2}$ hybridised with no lone pair of electrons on central atom, $N$. Whereas, $N_{3}, N O_{2}^{-}$ and $CO_{2}$ are sp hybridised with a linear shape.
