Answer:

Both ammonia and water have sp3 hybridisation. ... The repulsion between a lone pair and bond pair is more than repulsion between two bond pairs of electrons. Because there is one lone pair in NH3, therefore the bond angle is reduced from 109028' to 107028' due to distortion.

Answer:

Explanation:In H2O there are two lone pairs on oxygen while in ammonia there is only one lone pair.so due to more lone pair - lone pair repulsion in water it reduces its angle.Moreover lone pair -bond pair repulsion is much less in NH3 so its angle is less.
