Alkanes convert to haloalkanes using Br2cap B r sub 2 Cl2cap C l sub 2 under ultraviolet (UV) light. Electrophilic Addition: Alkenes react with HBrcap H cap B r HClcap H cap C l Br2cap B r sub 2 to form haloalkanes. Hydration: Alkenes react with steam ( H2Ocap H sub 2 cap O ) and a phosphoric acid ( H3PO4cap H sub 3 cap P cap O sub 4 ) catalyst to produce alcohols. 2. Alcohols and Carbonyls

At A2 level, you are expected to use more advanced and selective reactions, not just the ones from AS. As one examiner observed: Chemsheets Organic Synthesis Problems Answers

Which or functional group is giving you trouble?

For example, a typical problem might ask: "Synthesize butanoic acid starting from 1-bromopropane."

) adds exactly one carbon atom to a haloalkane, forming a nitrile. Step 2: Identify the Functional Groups

Start by comparing the starting material to the target product. Ask yourself: Have we added carbon atoms? Have we removed oxygen? Has the oxidation state changed?

Which specifications are you following (e.g., AQA, OCR, Edexcel)? If you share with third parties, their policies apply

Organic synthesis is the art of building complex organic molecules from simpler, commercially available starting materials. In an A‑Level context, synthesis problems typically ask you to:

The difficulty escalates quickly, incorporating reactions like nucleophilic substitution, elimination, oxidation, reduction, and addition-elimination.

Ensure your reactions yield the correct isomer. For instance, adding

As they triumphantly held up their completed worksheets, Professor Thompson walked into the lecture hall, a sly grin on his face. "Well done, students," he said. "You've demonstrated not only your knowledge of organic synthesis but also your detective skills. The answers were indeed hidden in plain sight."
