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.

Substitution reactions of alkyl halides: two mechanisms
WebJan 28, 2024 · Although halide ions (particularly iodide and bromide ions) are strong nucleophiles, they are not strong enough to carry out substitution reactions with alcohols … WebTranscribed image text: Choose the best explanation why vinyl and phenyl halides do not undergo SN2 reactions: The back-side is inaccessible. The π bond changes the polarity of the C − X bond. Nucleophiles attack the π bond before halide displacement. The carbon is too electron-rich.
