Question

Some of the properies of the two species `NO_(2)^(-)` and `H_(3)O` are described below which one of them is correct ?
A. Dissimilar in hybridization for the central atom with different atom
B. Isostructual with the same hybridization for the central atom
C. Isostructural with the difference hybridization for the central atom
D. Similar in hydridization for the central atom with defferent structure.

Answer 1

Correct Answer - a
Appliying the formula
`X = (1)/(2) [V.E + MA - C + a]`
For `NO_(3)^(-),X = (1)/(2) [5 + 0 - 1] = 3`
Hybridisation `= sp^(2)` , structure planar triangular
For `H_(3)O^(+) , X = (1)/(2) [6 + 3 - 1 + 0]= 4`
`rArr sp^(3)` hybridisation , pyramidal structure .Thus hybridisation and the structure are different.
