Study Notes
- Alkyl halides (except fluorides) can be reduced with zinc and dilute hydrochloric acid to give alkanes.
- Alkyl halides can also react with sodium metal in dry ethereal solution to produce higher alkanes through the Wurtz reaction.
- The Wurtz reaction is used for preparing higher alkanes with an even number of carbon atoms.
- Alkenes react with cold, dilute aqueous potassium permanganate to produce vicinal glycols, used to test for unsaturation.
- Polymerization of ethene molecules at high temperature and pressure with a catalyst produces polythene, a polymer used in plastic bags and other products.
