• # question_answer 57) Some of the properties of the two species, $NO_{3}^{-}$and${{H}_{3}}{{O}^{+}}$are described below. Which one of them is correct? A)  Dissimilar in hybridization for the central atom with different structureB)  Isostructural with the same hybridization for the central atomC)  Isostructural with different hybridization for the central atomD)  Similar in hybridization for the central atom with different structure

Applying the formula. $X=\frac{1}{2}[V.E+MA-C+a]$ For $NO_{3}^{-},X=\frac{1}{2}[5+0-0+1]=3$ Hybridisation$=s{{p}^{2}},$structure planar triangular For ${{H}_{3}}{{O}^{+}},X=\frac{1}{2}[6+3-1+0]=4$ $\Rightarrow s{{p}^{3}}$hybridisation, pyramidal structure. Thus hybridisation and the structures are different.
