  1. Question 1

    Q1. Propene is treated with anhydrous hydrogen bromide (HBr). Following the standard rule for electrophilic addition in PTB, what is the major organic product formed?

    • A) 1-Bromopropane
    • B) 2-Bromopropane
    • C) 1,2-Dibromopropane
    • D) 2,2-Dibromopropane

    Answer: 2-Bromopropane

    Explanation: Markownikoff's rule adds the halogen to the carbon with fewer hydrogens. 1-bromopropane is tempting but is the anti-Markownikoff product formed with peroxides.
