$BF_3$

Vedclass · Answer

(B) The dipole moment of a molecule is zero if the vector sum of all individual bond dipoles is zero. $BF_3$ has a trigonal planar geometry with three $B-F$ bonds at $120^{\circ}$ to each other. The resultant dipole moment of two $B-F$ bonds is equal and opposite to the third $B-F$ bond,resulting in a net dipole moment of $0$. $CH_2Cl_2$ is tetrahedral with a net dipole moment due to different electronegativities of $H$ and $Cl$. $NF_3$ has a pyramidal geometry with a lone pair on $N$,leading to a non-zero dipole moment. $ClO_2$ is bent and has a non-zero dipole moment.
