Q21 / 155 · WBJEE 2021 · Chemistry

The $\mathrm{H}_{3} \mathrm{O}^{+}$ion has the following shape

A
Tetrahedral
Correct answer
B
Pyramidal
C
Triangular planar
D
"T" shaped

Solution

$\mathrm{H}_{3} \mathrm{O}^{+}$ total valence $e^{-1}$ count $\begin{array}{l} \mathrm{O}+\mathrm{H}+\mathrm{H}+\mathrm{H}-\mathrm{e}^{-1}=8 \\ 2,6 \quad 1 \quad 1 \quad 1 \end{array}$ using Lever rule $2|8| 4 \leadsto$ sp $^{3}$ hybrid $(0)$ $\frac{8}{x}$

Hence, the correct answer is option: 'B'.
