$NH_3$

Vedclass · Answer

(B) The dipole moment of a molecule depends on its geometry and the electronegativity difference between the atoms. $BF_3$ has a trigonal planar geometry,and due to its symmetry,the individual bond dipoles cancel each other out,resulting in a net dipole moment of $0 \ D$. $NH_3$ has a trigonal pyramidal geometry with a lone pair on the nitrogen atom. The bond dipoles of the $N-H$ bonds and the lone pair dipole point in the same direction,resulting in a high net dipole moment of approximately $1.47 \ D$. $NF_3$ also has a trigonal pyramidal geometry,but the bond dipoles of the $N-F$ bonds point in the opposite direction to the lone pair dipole,which partially cancels the net dipole moment,resulting in a lower value of approximately $0.24 \ D$. $B_2H_6$ (diborane) is a non-polar molecule due to its bridge-bonded structure,resulting in a net dipole moment of $0 \ D$. Therefore,$NH_3$ has the highest dipole moment.

Which of the following molecules has the highest dipole moment?
