If B-Cl bond has a dipole moment, explai | Class 11 Chemistry Chapter The p Block Elements, The p Block Elements NCERT Solutions

Question:

If B-Cl bond has a dipole moment, explain why BCl3 molecule has zero dipole moment.

Answer:

As a result, the difference in the electronegativities of B and Cl, the B-Cl bond is polar in nature. However, the BCl3 molecule is non-polar. This is because BCl3 is trigonal planar in shape. It is a symmetrical molecule. Hence, the respective dipole-moments of the B-Cl bond cancel each other, therefore causing a zero-dipole moment.
