$NH_3$

Vedclass · Answer

(C) The dipole moment of $CO_2$ is $0 \, D$ because it is a linear molecule where the bond dipoles cancel each other.The dipole moment of $CH_4$ is $0 \, D$ because it is a symmetrical tetrahedral molecule where the bond dipoles cancel each other.In $NH_3$,the bond dipoles of the three $N-H$ bonds and the lone pair on $N$ are in the same direction,resulting in a net dipole moment of $1.46 \, D$.In $NF_3$,the bond dipoles of the three $N-F$ bonds are in the opposite direction to the lone pair dipole,which significantly reduces the net dipole moment to $0.24 \, D$.Therefore,$NH_3$ has the maximum dipole moment among the given molecules.

Which of the following molecules has the maximum dipole moment?
