The Markovnikov product resulting from an addition reaction to an unsymmetrical alkene is formed because _____________.
A) the product is statistically favored
B) steric hindrance favors its formation
C) the reaction proceeds via the more/most stable carbocation
D) the reaction forms the more/most stable product
E) All of the above are valid reasons

Question

Quizplus · Accepted Answer

The Markovnikov product is formed due to the reaction proceeding via the more or most stable carbocation intermediate. The stability is determined by the number of alkyl groups bonded to the carbocation, which increases the stability. Therefore, the carbocation intermediate will form on the carbon atom with the more number of alkyl groups, leading to the Markovnikov product. The other options are not significant factors in determining the Markovnikov product.
