Question
Out of $H_2O$ and $H_2S,$ which one has higher bond angle and why?
✓

Answer

Bond angle of $H_2O$ is larger, because oxygen is more electronegative than sulphur therefore bond pair electron of $O–H$ bond will be closer to oxygen and there will be more bond-pair bond -pair repulsion between bond pairs of two $O–H$ bonds.
