Some of the properties of the two species `NO_(2)^(-)` and `H_(3)O^(+)` are described below which one of them is correct ?

Options

A. Dissimilar in hybridization for the central atom with different structures
B. Isostructural with same hybridization for the central atom
C. Isostructural with different hybridization for the central atom
D. Similar in hybridization for the central atom with different structures.

Answer

A

Explanation

`NO_3^(-)` ion has a planar structure and nitrogen atom in it is `sp^2` hybridised whereas in `H_3^(+)O` central oxygen atom is `sp^3` hybridised and `H_3^(+)O` has tetrahedral structure
