CHEM 341 Chapter Notes - Chapter 12: Lithium Aluminium Hydride, Sodium Borohydride, Alkyne
Document Summary
Is an element more electronegative than carbon z oxidation an increase in the number of c z bonds or a decrease in the number of c h usually c o bonds bonds more oxygen less hydrogen. There are three types of l hz simplestreducing reagent catalyst. 2 add two photonsand two electrons w a substrate where the source of electrons and liquid ammonia alkali metal. Nhs is in the presence of a metal is ex the source of protons. 2mhz 7 2nh t 2 e z a e9hilivalent of for reduction. 3 add hydride h and a proton ht common hydrides are sodium borohydride nabhu and lithium aluminum hydrides. Hydrogenation reactions are exothermic because the bonds in the product are stronger than bonds in the starting materials metal hydride reagents can act as because they contain polar metal hydrogen bonds that place a partial negative charge on hydrogen.
