Question:

$\text{The correct statement regarding the bond angle of } \text{H}_2\text{O} \text{ and } \text{H}_2\text{S} \text{ is:}$

Options:

1. $\text{Both have the same bond angle.}$
2. $\text{Bond angle of } \text{H}_2\text{O} \text{ is larger than that of } \text{H}_2\text{S}$ (Correct)
3. $\text{Bond angle of } \text{H}_2\text{O} \text{ is smaller than that of } \text{H}_2\text{S}$
4. $\text{None of the above.}$

Solution:

$\text{HINT: Bond angle of } \text{H}_2\text{O} > \text{H}_2\text{S}$ $\text{Explanation:}$ $\text{Bond angle of } \text{H}_2\text{O} (\text{H} - \text{O} - \text{H} = 104.5°) \text{ is larger than that of } \text{H}_2\text{S} (\text{H} - \text{S} - \text{H} = 92°)$ $\text{Because oxygen is more electronegative than sulphur.}$ $\text{Therefore, bond pair electron of O-H bond will be closer to oxygen and there will be more bond-pair repulsion between bond pairs of two O-H bonds.}$
