Final answer:
The major organic product of the reaction of 2-methyl-2-pentene with H2O in the presence of H2SO4 is 2-methyl-2-pentanol, which features a hydroxyl group replacing the double bond in the original alkene.
Step-by-step explanation:
The reaction of 2-methyl-2-pentene with water in the presence of H2SO4 is an example of acid-catalyzed hydration, a common electrophilic addition reaction in organic chemistry. In the presence of a strong acid, like sulfuric acid, the alkene will react to form an alcohol. Given that 2-methyl-2-pentene is symmetric, there is no regioselective issue in this case. The major organic product will have the same number of carbon atoms and will include a hydroxyl (-OH) group at the position of the former double bond. The structure of the major product is 2-methyl-2-pentanol.
Regarding the reference to the acetyl group (Ac), it’s worth noting that the acetyl group is a functional group with the chemical formula CH3CO. It is derived from acetic acid and is often represented in chemical structures as -COCH3.
