difference between aromatic and aliphatic compounds?
Aliphatic compounds are hydrocarbon chains - strings of carbon atoms connected to each other with single, double or triple bonds. Aliphatic compounds could be straight chain structures like alkanes or cyclic structures, like cycloalkanes.
Aromaticity is a chemical property in which a conjugated ring of unsaturated bonds, lone pairs, or empty orbitals exhibit a stabilization stronger than would be expected by the stabilization of conjugation alone. It can also be considered a manifestation of cyclic delocalization and of resonance.
