Addition of HBr to propene **without peroxide** gives mainly:
A1-bromopropane (anti-Markownikoff)
B2-bromopropane (Markownikoff — Br adds to more substituted C)
C1,1-dibromopropane
DOnly allyl bromide
Answer & Solution
Correct answer: B. 2-bromopropane (Markownikoff — Br adds to more substituted C)
CH₃-CH=CH₂ + HBr → CH₃-CHBr-CH₃ (2-bromopropane) by Markownikoff (Br on more substituted C, forming the more stable 2° carbocation). Without peroxides, ionic addition gives this product.
