Concept

Problem: In the following Robinson Annulation, compound A could be formed but is not a final product of the reaction. Why? a) A is formed irreversibly, but only in small amounts contributing to a lower yield of the reaction. b) A is too strained and is never formed. c) A is formed reversibly, but cannot undergo elimination, so it reverts back the prior intermediate. d) A can only be formed from the less favorable enolate and is therefore only a minor product of the reaction. e) The bonds in A are way too long and a molecule would never want to look that silly, so it doesn’t form.
