Aside from using standard alkyl halides with , which of the following combinations of reagents can s — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

Alkenes treated with strong acids (like $HF$ or $H_2SO_4$) undergo protonation to generate carbocations. Alcohols treated with Lewis acids (like $BF_3$) or protonic acids also generate carbocations via the loss of water/complex. Both can act as excellent electrophiles for FC alkylation. Aryl and vinyl halides do not form stable carbocations and cannot be used.
