Step-by-step explanation
Statement A is correct. Alcoholic KOH provides alkoxide ions which are stronger bases than hydroxide ions. Furthermore, alcohol is a less polar solvent than water, which decreases the solvation of the base, making it more effective for elimination reactions over substitution.
Statement B is incorrect. The reactivity towards the mechanism depends on the stability of the intermediate carbocation. The carbocation is more stable than due to extended resonance stabilization from two phenyl rings. Thus, is more reactive than .
Statement C is incorrect. Aryl halides are much less reactive towards nucleophilic substitution than alkyl halides due to the partial double bond character of the C-X bond arising from resonance, as well as the hybridization of the carbon atom.
Statement D is incorrect. Allyl chloride () contains a carbon-carbon double bond, making it a haloalkene, not a haloalkyne.
Statement E is correct. Alkyl chlorides () can be easily prepared from alcohols () using . However, phenols () do not react with to give aryl chlorides because the C-O bond in phenol has a partial double bond character due to resonance, making it difficult to cleave.
Therefore, only statements A and E are correct.
