Which of the following pairs is isostractural (i.e having the same shape and hybridization ?

Options

A. `[BCl_(3)and BrCl_(3)]`
B. `[NH_(3)and NO_(3)^(-)]`
C. `[NF_(3)and BF_(3)]`
D. `[BF_(4)^(-)and NH_(4)^(+)]`

Answer

D

Explanation

`[BF_(4)]^(-)and [NH_(4)]^(+)` one iso-strucrural
`[BF_(4)]^(-):H=1//2[3+4-0+1]=4(sp^(3))`
`[NH_(4)]^(+):H=1//2[5+4-1+0]=4(sp^(3))`
