MOLECULAR POLARITYFIELD NOTE 61 / 175
Is C8H8 polar or nonpolar?
Styrene (C8H8) is nonpolar because its phenyl and vinyl groups contain only C and H.

Why C8H8 is nonpolar
Styrene joins a benzene ring to a vinyl CH=CH2 group. It has no strongly polar heteroatom group and is conventionally treated as a nonpolar hydrocarbon.
What to notice
Styrene and ethylbenzene differ by one C=C bond. That changes reactivity and the 3D shape, even though both lack a polar functional group.
