Mechanism of Addition Reaction of 2-Hexene with HBr

Medium Organic Chemistry Addition Reactions

In an organic chemistry lab, a student conducts an addition reaction by treating 2-hexene with hydrogen bromide (HBr) under acidic conditions. The student observes the formation of 2-bromohexane as the major product. Understanding the mechanism of this reaction is vital for predicting the products formed in similar reactions. Which of the following statements regarding the mechanism of this addition reaction is correct?

The electrophile is generated by the protonation of 2-hexene.

The reaction proceeds via a free radical mechanism.

The intermediate formed during the reaction is a carbocation.

The addition is stereospecific, leading to only the trans isomer.
