Question

which of the following is true of the mechanism of the acid-catalyzed addition of H2O to an alkene Which of the following is true of the mechanism of the acid-catalyzed addition of H20 to an alkene? Select one: OA. H20 nucleophilically bonds to the C-C group in a first, slow step, followed by a rapid protonation of a carbon anion. O B. OHt electrophile from H20 first bonds to C-C, followed by attachment of H: in a stereoselective ANTI addition. O C. H20 bonds to C-C in a concerted, SYN addition process. O D. The first step is the slow attachment of Ht to the C-C group to form a carbocation.

Explanation / Answer

In the acid cataysed hydration of the alkene . the first step is the addition of the H+ to the alkene to form the carbocation. in the second step the addition of water to carbocation is the simple acid base reaction and in the third step the H+ leaves and we get the alcohol.

So, option D is correct here.
