Out of `H_(2)O` and `H_(2)S` which one has higher bond angle and why ?

Explanation

(i) Bond angel of `H_(2)O(H-O-H=104.5^(@))` is larger than that of `H_(2)S(H-S-H=92^(@))`.
(ii) Since oxygen is more electronegative than sulphur, therefore bond pair electrons of O-H bond will be closer to oxygen which will be little away from the sulphur atom.
(iii) As a result, bond pair - bond pair repulsions between bond pairs of two O-H bonds would be stronger than in the S-H bonds.
