But precipitate only appears halogen leaves – so reaction must be nucleophilic substitution. Water is the nucleophile here. 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 .

– The carbon bearing the halogen determines the reaction pathway. Water is the nucleophile here

can do both, depending on the solvent and temperature.

For primary halogenoalkanes, the mechanism generally follows these steps: The nucleophile ( ) attacks the Cδ+cap C raised to the delta plus power from the side opposite the halogen. A transition state forms where the bond is forming while the bond is breaking. The halide ion ( X−cap X raised to the negative power ) leaves (the "leaving group"). 5. Elimination Reactions
