MOLECULAR POLARITYFIELD NOTE 58 / 175
Is C7H8O polar or nonpolar?
Benzyl Alcohol (C7H8O) is polar because its side-chain O–H and C–O bonds create a polar alcohol end.

Why C7H8O is polar
Benzyl alcohol is C6H5–CH2–OH: the hydroxyl group is on the carbon beside the ring, not directly bonded to the ring. Its O-containing end has a net dipole.
What to notice
Benzyl alcohol and phenol both have a benzene ring and OH, but phenol bonds O directly to the ring; their chemical behavior differs.
