MOLECULAR POLARITYFIELD NOTE 15 / 175
Is Bromobenzene (C6H5Br) polar or nonpolar?
Bromobenzene (C6H5Br) is polar because its single C–Br bond breaks the equivalent positions of benzene.

Why C6H5Br is polar
One bromine replaces a hydrogen on the aromatic ring. Bromine's C–Br bond and the five C–H directions do not have matching dipole strengths, so the molecule retains a net dipole even though the ring is nearly planar.
What to notice
Fluorobenzene, chlorobenzene, and bromobenzene have the same one-substituent ring pattern. The halogen changes bond polarity, while the broken benzene symmetry is shared.
Common questions about C6H5Br
