Phenyl halide

WebA phenyl is a hydrophobic group. Phenyl groups sometimes resist oxidation and reduction. Phenyl groups (like all aromatic compounds) have elevated stability relative to equivalent bonding in aliphatic (non-aromatic) groups. This improved stability is due to the unique characteristics of aromatic molecular orbitals.
