Select the route that would most likely produce the desired results from the given starting material.

I.(1) H₂SO₄ and heat; (2) HBr II.(1) KOH in ethanol; (2) HBr
III) (1) H₂SO₄ and heat; (2) HBr + peroxides
IV) (1) potassium tert-butoxide in tert-butanol; (2) HBr + peroxides

Quizplus · Accepted Answer

The reaction requires anti-Markovnikov addition of HBr. This can be achieved by using a radical initiator such as peroxides. Therefore, the route that includes (1)potassium tert-butoxide in tert-butanol; (2)HBr + peroxides is the best choice as it will produce the desired anti-Markovnikov product.
