CARBOCATION REARRANGEMENT 2

Alkenes undergo electrophilic addition with many reagents like HX, H_2O , HOCI etc. Except in the case of addition of X_2^(-) in other additions carbocation is formed as intermediate. The rate of such reactions depends on the stability of carbocation. Rearrangements and ring expansion are also common in such reactions. Propene on reaction with HI in presence of peroxide will give

Rearrangement Reactions OF Carbocations(Ring Expansion And Ring Contraction Reaction)

Acid catalysed hydration of alkene give alcohol. In thic reaction addition of water takes place according to Markownikov's rule. Since intermediate carbocation is formed in this reaction, rearrangment of carbocation takes place. In oxymercuration-demercuration reaction hydration of alkene takes place according to markownikov's rule. Oxymercuratio-demercuration-dermercuration no rearrangement is possible. in hydroboration-oxidation hydration of alkene takes place according to anti marjownikow's addition. in HBO reaction rearrangement is not possible. both in oxymercuration-demercuation and hydroboration-oxidation, intermediate carbocation are not formed.
