MOLECULAR POLARITYFIELD NOTE 62 / 175
Is C8H8O polar or nonpolar?
Acetophenone (C8H8O) is polar because its aryl ketone C=O bond creates an oxygen-rich end.

Why C8H8O is polar
Acetophenone has a phenyl ring on one side of a carbonyl carbon and CH3 on the other. The C=O bond gives the molecule a strong direction of charge separation.
What to notice
Unlike benzaldehyde, acetophenone's carbonyl carbon is bonded to two carbon groups, making it a ketone rather than an aldehyde.
