🤓 Based on our data, we think this question is relevant for Professor Chen's class at CSU.
We’re being asked to determine the most stable intermediate of the given reaction.
Recall that alkenes are converted to alcohols via acid-catalyzed hydration, which occurs in three steps:
(1) protonation – the alkene is protonated by the acid catalyst, forming a carbocation intermediate. This follows Markovnikov’s rule, which states that the more stable carbocation is formed.
Also, since a carbocation is formed during the reaction, the carbocation may rearrange into a more stable one.
(2) nucleophilic attack – water in and attacks the positively-charged carbon. The stereochemistry for this reaction is unknown since the nucleophile can attack either side of the empty p-orbital.
(3) deprotonation – the conjugate base deprotonates the oxonium ion, reforming the acid catalyst.
Write a mechanism for the following reaction.
