Current Question (ID: 20966)

Question:

$\text{Total number of lone pair of electrons in } \text{I}_3^- \text{ ion are:}$

Options:

1. $3$
2. $6$
3. $9$
4. $12$

Solution:

$\text{Hint: The hybridization of I in } \text{I}_3^- \text{ is } \text{sp}^3\text{d.}$ $\text{Explanation:}$ $\text{The hybridization of I as follows: } S. N = \frac{1}{2}[V + M + A - C] = \frac{1}{2}[7 + 2 + 1 - 0]$ $S.N. = 5$ $\text{The hybridization of I in } \text{I}_3^- \text{ is } \text{sp}^3\text{d.}$ $\text{The shape is linear and the geometry is trigonal bipyramidal. The structure is as follows:}$ $\begin{array}{c} \text{[I} \cdots \text{I} \cdots \text{I]} \rightarrow \text{I} \cdots \text{I} \cdots \text{I} \end{array}$ $\text{In } \text{I}_3^-, \text{ total nine pairs of lone pairs are present. So, option 3 is the correct answer.}$
