Aliphatic and Aromatic alcoholsWatch
Aromatic on the hand are rings with an alcohol on, i.e. Phenol (C6H5OH)
So rule of thumb: Straight aliphatic, non-straight aromatic.
Aromatic alcohol = aromatic (has to be cyclic, planar and fully conjugated - like phenol)
Aliphatic is just a general term for compounds that are not aromatic.
and aliphatic is everything else e.g. propanol, ethanol, cyclohexane
