In the addition reaction of HI to 2-methyl-2-butene, the Markovnikov addition mechanism involves:

Question

Quizplus · Accepted Answer

The Markovnikov addition mechanism involves the formation of a carbocation intermediate on the more substituted carbon atom, in this case, carbon two (C-2) of 2-methyl-2-butene. The proton from HI then adds to the carbocation, forming 2-iodo-2-methylbutane as the product. Choice A and B are incorrect because iodide ion or iodine atom does not initiate the attack, but rather the carbocation is formed first. Choice C is incorrect because there is no isomerization involved in the Markovnikov addition mechanism. Choice E is incorrect because forming a carbocation at carbon three (C-3) would not lead to the Markovnikov product.
