Answer:
Because of one lone pair in ammonia molecule, the distorted tetrahedral become pyramid with bond angle is 107o and there is more lp-lp repulsion in water molecule the distorted tetrahedral become V-shape with bond angle 104.5o

Answer:
The central atom in ammonia and water molecules have1 and 2 lone pairs of electrons respectively.
Lone pairs distort the molecular geometry. Lone pair-bond pair repulsion is stronger than bond pair-bond pair repulsion. The bond angle of ammonia reduces from 109.5
o
(tetrahedral) to 107
o
.
In the case of a water molecule, the bond angle decreases to 105.4
o
as more number of lone pair-bond pair repulsions are present.
