ABCD
Answer: A → III, A → IV, B → V, C → I, C → II, D → III
Solution
A) The reaction shown is a Friedel-Crafts acylation followed by coupling, involving both substitution and coupling mechanisms. B) This reaction proceeds through a carbocation intermediate. C) The reaction produces a racemic mixture through an addition mechanism. D) This is a substitution reaction.
