1.	In both water and diethyl ether, the central atom viz. O-atoms has same hybridisation . Then why have they different bond angles ? Which one has greater bond angle ?
Answer» SOLUTION :The central atom in each case is `sp^(3)` hybridized . Hence , expected bond angle in each sase is `109^(@)28`' . The two pairs present on O-atom repel the bond pairs and hence TEND to reduce the bond angle . However, the greater repulsions between two ethyigroups, in diethyi ether than between the two H-atoms in `H_(2)O` RESULT in greater bond angle `(110^(2))` in diethyi ether than that in `H_(2)O` `(104.5^(@))` .
