11.15. If B–Cl bond has a dipole moment, explain why molecule has zero dipole moment.
Due to differences in electronegativities of Boron and chlorine, the partial charges develop in B-Cl bond. is a non-polar compound. This molecule is trigonal planner shape (symmetrical) and we know that dipole moment is a vector quantity. In fig. we can see that, they can cancel out each other.
