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.
