Question
Why does a H+ ion attacking a carbon-carbon double bond add to the carbon with the least number of substituents?
Correct Answer
Option D is the correct answer.
Detailed Explanation
According to Markovnikov's rule, the electrophile (H+) adds to the carbon with the greater number of hydrogens (less substituted carbon) because this leads to the formation of the more stable carbocation intermediate (more substituted carbocation).
