Some of the properties of the two species, $NO_{3}^{-}$ and $H_{3} O^{+}$ are described below. Which one of them is correct?NEET 2010 (Mains)

Options:

Answer:

Solution:

$In NO_{3}^{-}, H = \frac{1}{2} [5 + 0 - 0 + 1] = 3$ Thus, in $NO_{3}^{-}$ , the central atom is $sp^{2}$ hybridised and it has trigonal planar geometry.
In $H_{3} O^{+}$ , $H = \frac{1}{2} [6 + 3 - 1 + 0] = 4$ Thus, $O$ is sp $^{3}$ hybridised in $H_{3} O^{+}$ and $H_{3} O^{+}$ has pyramidal geometry due to the presence of one lone pair of electrons.
