If $B-Cl$ bond has a dipole moment, explain why $BCl_3$ molecule has zero dipole moment.
Option A
Option B
Option C
Option D
Solution
As a result of the difference in the electronegativities of $B$ and $C l$, the $B-Cl$ bond is polar in nature. However, the $BCl_3$ molecule is non-polar. This is because $BCl_3$ is trigonal planar in shape. It is a symmetrical molecule. Hence, the respective dipole-moments of the $B-Cl$ bond cancel each other, thereby causing a zero-dipole moment.
