Vedclass · Answer

(C) $BF_3$ is non-polar due to its symmetrical trigonal planar geometry,where the individual bond dipole moments cancel each other out,resulting in a net dipole moment of $0 \ D$.In $NF_3$ and $NH_3$,both have a trigonal pyramidal geometry with a lone pair on the nitrogen atom.In $NH_3$,the dipole moments of the three $N-H$ bonds and the lone pair are in the same direction,leading to a large net dipole moment.In $NF_3$,the dipole moments of the three $N-F$ bonds are in the opposite direction to the lone pair dipole,which reduces the net dipole moment.Therefore,the correct order of increasing dipole moment is $BF_3 < NF_3 < NH_3$.

Identify the option in which the molecules are arranged in the correct order of their dipole moments.
