Question
Which of the following statements are accurate regarding "pseudo rearrangements" or allylic rearrangements?
💡 Solution & Explanation
Allylic rearrangements (pseudo rearrangements) do not involve the actual migration of atoms or groups along the carbon skeleton (A is false). Instead, they occur because the intermediate (carbocation, carbanion, or radical) is delocalized by resonance (B is true). Because the charge/radical is shared across multiple carbons, an incoming reagent can attack at different sites, yielding multiple isomeric products without any actual atomic shifting (C is true). They can occur under acidic, basic, or neutral conditions (D is false).
