A2 Organic Synthesis Reaction Web — A Level Chemistry 9701 — Frequently Asked Questions
Which A2 conversions come up most often in synthesis questions?
Nitration of benzene followed by reduction to phenylamine, acyl chloride formation with SOCl₂, and nitrile hydrolysis or reduction. These three appear again and again because each one changes the functional group in a way nothing else can.
Do I need the AS reaction web as well?
Yes — most Paper 4 synthesis routes pass through AS chemistry on the way. The AS reaction web is linked below and the two are designed to be used side by side.
