Phenol is more acidic than alcohols due to resonance stabilization of the phenoxide ion, so it reacts more vigorously with sodium metal.

Elimination (E₂) with alcoholic KOH favors tertiary halides due to stable alkene formation. (CH₃)3CBr reacts fastest.

SN₂ favors primary halides due to less steric hindrance. CH₃CH₂CH₂CH₂I (iodide) is most reactive due to the best leaving group.
