1.	Although geometries of `NH_(3) and H_(2) O ` molecules are distorted tetrahedral, bond angle in water is less then that of ammonia. Discuss .
Answer» In ` NH_(3)`, there is only one lone pair on N-atom to repel the bond pairs whereas in ` H_(2)O` , there are two lone pairs on O-atom to repel the bond paris . Hence the repulsions on bond pairs are greater in ` H_(2) O ` than in ` NH_(3)` and hence the bond angle is less.
