Question:

The correct increasing order of bond angles in the following species is:

Options:

1. $\text{Cl}_2\text{O} < \text{ClO}_2 < \text{ClO}_2^-$
2. $\text{ClO}_2^ - < \text{Cl}_2\text{O} < \text{ClO}_2$
3. $\text{Cl}_2\text{O} < \text{ClO}_2^ - < \text{ClO}_2$ (Correct)
4. $\text{ClO}_2^ - < \text{Cl}_2\text{O} < \text{ClO}_2$

Solution:

$\text{HINT: Bond angle } \propto \frac{1}{\text{Number of lone pairs}}$ $\text{Explanation:}$ $\text{As the number of lone pairs of electrons increases, the bond angle decreases due to repulsion between lp-lp. Moreover, as the electronegativity of the central atom decreases, the bond angle decreases.}$ $\text{ClO}_2^ - \text{ (two lone pairs)} < \text{Cl}_2\text{O} \text{ (two lone pairs)} < \text{ClO}_2 \text{ (one lone pair)}$ $\text{Hence, the order of bond angle is } 110^\circ, 111^\circ, 118^\circ$
