some alkenes do not undergo hydration but they do so if  we use conentrated acid why does hydration of alkene depend on the concentration of acid used?

Answers : (1)


Dear manish,

Addition is acid is to tranfer the the proton to the alkene to form a carbocation.In acid catalyzed addition of water (hydration), the acid which actually transfers the proton to the alkene is normally the solvated hydronium ion.Water, itself, is too weak an acid to transfer the proton to the alkene, so acid catalysis is essential.
