Question: Which reaction mechanism is involved in the hydration of alkenes?

Options:

Correct Answer: Electrophilic addition

Solution:

The hydration of alkenes involves an electrophilic addition mechanism where water adds across the double bond.

Which reaction mechanism is involved in the hydration of alkenes?

Step 1: Identify the alkene, which is a molecule with a carbon-carbon double bond.
Step 2: Understand that hydration means adding water (H2O) to the alkene.
Step 3: Recognize that the reaction starts with the double bond in the alkene acting as a nucleophile, which means it can donate electrons.
Step 4: Water (H2O) acts as an electrophile, meaning it can accept electrons.
Step 5: The double bond attacks the hydrogen atom of water, breaking the double bond and forming a carbocation (a positively charged carbon).
Step 6: The hydroxide ion (OH-) from the water molecule then attacks the carbocation, resulting in the formation of an alcohol.
