      Out of  and, which one has higher bond angle and why?

    Answer:

                        Bond angle of (1-1?0?H = 104.5°) is larger than that of (H?S?H = 92°) because oxygen is more electronegative than sulphur therefore, bond pair electron of 0?H bond will be closer to oxygen and there will be more bond pair?bond pair repulsion          between bond pairs of two 0?H bonds.
