Out of H2O and H2S which one has higher bond angle and why ?


Bond angle of H2H - O - H = 104.5° is larger than that of H2H - S - H = 92°
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 repulsion between bond pairs of two O - H bonds.
