Explanation:

Hydroxylation of alkene compounds is called a hydration reaction. The reaction occurs in the presence of a strong acid catalyst to protonate the organic compound similar to Markovnikov's addition forming a carbocation as an intermediate. A water molecule nucleophilicly bonds to the carbocation intermediate. A proton is lost from the positively charged oxygen to a chloride ion yielding the alcohol product and regenerating the acid.

Example Question #21 : Help With Alkene Reactions

What is the product of the reaction shown?

Image7

Possible Answers:

Correct answer:

Explanation:

The reaction is a catalytic hydrogenation of an alkene using a palladium (Pd) catalyst. This reaction can be used to add a hydrogen atom to each carbon involved in a pi bond. The resulting molecule will be a an alkane.
