Which alcohol is formed by the hydration of 2-methyl-2-pentene?

Question

Quizplus · Accepted Answer

The hydration of 2-methyl-2-pentene is an example of a Markovnikov addition reaction. In such reactions, the proton (H+) adds to the less substituted carbon and the OH- group adds to the more substituted carbon. Hence, when 2-methyl-2-pentene is hydrated, the OH- group adds to the carbon that has more substituents attached to it (i.e., the carbon that is bonded to two additional methyl groups) to form 3-methyl-2-pentanol. The correct IUPAC name of the alcohol is 3-methylpentan-2-ol, which is closest to choice B.
