Question

Find the number of lone pairs on the central atom in the interhalogen compound ${\mathrm{IX}}_3$.

• A. $1$
• B. $2$
• C. $3$
• D. $5$

Answer 1

The correct option is B

$2$

Answer (C)

Explanation for correct option:

Hybridization of interhalogen compound=${\mathrm{IX}}_3={\mathrm{sp}}^3\mathrm{d}$

Structure: $3$ bond pairs and $2$ lone pairs, hence T shaped . Therefore, the central atom $1$ contain $2$ lone pairs.

The detailed diagram of ${\mathrm{ClF}}_3$, one of the interhalogen compound is given below:

Hence option (C) is the correct option
