Specifically for reagents and conditions (e.g., Side A: "Alkane to Halogenoalkane"; Side B: " Br2cap B r sub 2 , UV Light, Free Radical Substitution").
Does the product have more carbons than the starting material? If yes, you almost certainly need a nitrile intermediate (using KCNcap K cap C cap N Chemsheets Organic Synthesis Problems Answers
) or a Grignard reagent (though less common in standard A-Level). Specifically for reagents and conditions (e
You’ll notice that Chemsheets often uses the same "tricks," such as using PCl5cap P cap C l sub 5 to create acyl chlorides or using LiAlH4cap L i cap A l cap H sub 4 for tougher reductions. You’ll notice that Chemsheets often uses the same
However, moving from basic functional group knowledge to solving a "Chemsheets Organic Synthesis" worksheet can be a massive leap. This guide breaks down how to approach these problems and where to focus your revision to find the right answers. Why Organic Synthesis Problems Are Challenging
