Question

How many lone pairs are present in $Cl{I}_3$ ?

• A. 11
• B. 8
• C. 5
• D. 4

Answer 1

The correct option is A 11

In $Cl{I}_3$, Cl is the central metal atom and have 2 lone pair on it.

$I^{-}$ is bonded with a chlorine atom and each iodine atom is having 3 lone pair on it.

Therefore, the total number of lone pairs = lone pair on $Cl$ + no. of iodine atom$\times$ lone pair on iodine atom.

so, total lone pairs = 2 + (3$\times$3) = 11 lone pairs

Hence, option A is correct.
