Vedclass · Answer

(C) The presence of a lone pair in $NH_3$ affects both its geometry and bond angle.According to $VSEPR$ theory,the repulsion between a lone pair and a bond pair is greater than the repulsion between two bond pairs.This lone pair-bond pair repulsion causes the $H-N-H$ bond angle to decrease from the ideal tetrahedral angle of $109.5^{\circ}$ to $107^{\circ}$.Consequently,the molecular shape changes from tetrahedral to trigonal pyramidal.
