Some of the properties of the two species, NO_(3)^(-) and H_(3)O^(+) are described below. Which one of them is correct?

Answer»

Dissimilar in hybridization for the central ATOM with DIFFERENT structures.
Isostructural withsame hybridization for the central atom
Isostructural with different hybridization for the central atom
Similar in hybridization for the central atom with different structure.

Solution :No. of electron pairsat the central atom =No. of atoms BONDED to it + 1/2[GROUP number of central atom - Valency of the central atom `+-` no. of electron]
No. of electron pairs at the central atom in
`NO_(3)^(-)=3+1/2[5-6-1]=3` (`sp^(3)` hybridisation)
No.of electron pairs at the central atom in
`H_(3)O^(+)=3+1/2[6-3-1]=4` (`sp^(3)` HYBRIDIATION)
