Document Summary

If its possible in the rxn to create a more stable carbocation then it will be created: oxymercu ration - Alkenes : hydrobo ration - oxidation gives anti mormovnikov product. : hydrogen goes to carbon with least hydrogens. Next can plane - only attach trans the only to product ! other. No . of alkene groups = speed of rxn . e. rich donate e- "s more nucleophilic alkene. Halohydrin same first step ( induced dipole a. 2nd step : hao attacks halonivm ion because it is the only base to deprotohate the alkene. Selectivity : in halohydrins , both added groups ( oh are are different and will attracted to the most have selectivity . substituted groups . Lh2 to create outdo propane ring use diazo methane becomes carbene carbene adds onto double bond to form the cyclo propane ring in a single step syn addition !
