WebThe phenyl group is hydrophobic. Phenyl groups tend to resist oxidation and reduction. Phenyl groups (like all aromatic compounds) have enhanced stability in comparison to equivalent bonding in aliphatic(non-aromatic) groups. This increased stability is due to the unique properties of aromatic molecular orbitals. [2] WebAlkyl: An alkyl group is an alkane substituent missing one hydrogen, with general formula CnH2n+1.
