Alkenes Properties Nomenclature Addition Reactions
Preparation of Alkenes • E2 - Elimination reactions of alkyl halides and tosylates (or mesylates) • E1 - Acid catalyzed dehydration of alcohols
Hydrogenation Data Helps to Determine StabilityDHhydrogenation of Alkenes
Markovnikov’s RuleThe addition of H-X across a double bond results in the more highly substituted alkyl halide as the major product.
Definitions • Regioisomers – two constitutional isomers that could result from an addition reaction. • Regiospecific – only one regiosisomer forms at the expense of the other. • Regioselective – both regioisomers are formed, but one is formed in preference.
