  1. Question 1

    Q1. The decreasing order of boiling points of alkyl halides is?

    • A) RI > RBr > RCl > RF
    • B) RF > RCl > RBr > RI
    • C) RCl > RBr > RI > RF
    • D) RBr > RI > RCl > RF

    Answer: RI > RBr > RCl > RF

    Explanation: Boiling points of alkyl halides increase with the size and polarizability of the halogen atom, hence RI > RBr > RCl > RF.
