Reactions Of Halogenoalkanes 1 Chemsheets Answers Exclusive

Chemsheets AS 1139 outlines that reactions of halogenoalkanes are determined by competition between nucleophilic substitution and elimination, heavily influenced by solvent and temperature conditions. Substitution occurs with aqueous reagents to form alcohols, while elimination to produce alkenes is favored by hot, ethanolic conditions. Review the content at scisheets.co.uk .

Q3: What is the product of the reaction between iodoethane and silver nitrate?

• Halogen exchange: RX + NaX' → RX' + NaX (often in acetone). Finkelstein reaction commonly converts alkyl chlorides or bromides to iodides (better leaving group) using NaI in acetone (NaCl/NaBr precipitate drives equilibrium). Useful to prepare more reactive haloalkanes for further reactions.

5. Reaction Rates and Silver Nitrate Test

• Equation: CH₃CHClCH₂CH₃ + H₂O → CH₃CH(OH)CH₂CH₃ + HCl
• Rate order: Tertiary > Secondary > Primary (because SN1 favored).
