Which of the following species has tetrahedral geometry?

A

`BH_4^(-)`

B

`NH_2^(-)`

C

`CO_3^(2-)`

D

`H_3O^(+)`

Text Solution

Verified by Experts

The correct Answer is:
A
`BH_4^(-) rArr 4 `bond pairs + 0 lone pair `rArr sp^3` hybridised = tetrahedral geometry
`NH_2^(-) = V `- shape
`CO_3^(2-)`= triangular planar
`H_3O^(+)` = pyramidal
