Among the following species identify the isostructural pairs :
`NF_3,NO_3^-,BF_3,H_3O^+,HN_3`
A. |
`[NF_3,NO_3^-] and [BF_3H_3O^+]` |
B. |
`[NF_3,HN_3^-] and [NO_3^-,BF_3]` |
C. |
`[NF_3,H_3O^+] and [NO_3^+ and BF_3]` |
![]() |
D. |
`[NF_3,H_3O^+] and [HN_3 , BF_3]` |
`NF_3` and `H_3O^+` have `sp^3` hybridisation; `NHO_3^ -` and `BF_4` have `sp^2` hybridisation.
