Markovnikov’s rule:
Alkenes undergo electrophilic addition reactions. They are triggered by the acid acting as an electrophile toward the π-electrons of the double bond.
Markovnikov’s rule states that when an unsymmetrically substituted alkene reacts with a hydrogen halide, the hydrogen atom adds to the carbon that has a greater number of hydrogens, e.g.,
What is the energy profile of the given reaction?

What is the energy profile of the given reaction?
The correct option is C
Markovnikov’s addition on alkene using HX is a 2 step process.
1st step involves the generation of carbocation and is a slow step whereas 2nd step involves attack of Nu(X−) to form product and is a fast process.
The step with the largest activation energy will be the rate-determining step. In the figure, the second step has larger activation energy and is, therefore, the rate-determining step.
∴ Energy profile of the given reaction has 2 peaks indicating 2 steps and 1st peak will be higher than 2nd indicating 1st step as slow.
So, the correct answer is (B).
