1.

The bond angle in H_2 O is 105^@but in H_2 S is 92^@ . Explain the difference.

Answer»

Solution :The larger size of the S atom compared with O atom, minimises the elcectron REPULSIONS and allows the BONDS in `H_(2)S` to be more purely p-type.
Moreover O in `H_(2)O` is `sp^(3)` hybridised but pure p-orbitals are USED by S of `H_(2)S`
