Core organic routes
Alkanes, alkenes, alcohols, haloalkanes, oxidation and two-stage synthesis.
OCR A organic chemistry
Organic synthesis games
Practise reagents, conditions and one-, two- and three-step routes from the OCR A specification. Choose Year 12, Year 13 or the full course before starting.
Advanced synthesis
Carbonyls, nitriles, amines, carboxylic acids, acyl chlorides, esters and amides.
Exam-board wording
The reagent rack follows OCR A content, including SOCl₂, nitrile chemistry and multi-stage routes.

What the games cover
Year 12 questions use the core OCR A reactions of alkanes, alkenes, alcohols and haloalkanes. Year 13 adds carbonyl reduction and addition, nitrile chemistry, amines, carboxylic acids, esters, acyl chlorides and amides.
Some paper routes are chemically possible but poor in the laboratory because they form mixtures. The feedback flags those cases instead of presenting them as sensible preparations.
