Why H-S-H bond angle in `H_(2)S` is smaller than `H-O-H` bond angle in `H_(2)O` ?

The H-N-H bond angle in NH_3 is greater than the H-As-H bond angle in AsH_3 .

The H-O-H bond angle in water is

When NH_(3) is treated with HCl, H-N-H bond angle

The H - O - O bond angle in H_(2)O_(2) (g) is

Bond angle in NH_(3) is more than in H_(2)O. Discuss

C-O-C bond angle in ether is more than H-O-H bond angle in water although oxygen is sp^(3) hybridised in both the cases. Explain

The bond angle in H_(2)S is 92^(@) . It suggest that :

The bond angle of H_(2)Se is best described as

Bond angle in H_(2)O(104.5^(@)) is higher than the bond angle of H_(2)S (92.1^(@)) . The difference is due to

The bond angle in H_(2)O molecule is .. .....
