  1. Question 1

    Q1. The order of boiling points of the following is: CH3CH2CH2OH, CH3CH2OCH3, CH3CH2CH3

    • A) CH3CH2CH2OH > CH3CH2OCH3 > CH3CH2CH3
    • B) CH3CH2CH3 > CH3CH2OCH3 > CH3CH2CH2OH
    • C) CH3CH2OCH3 > CH3CH2CH2OH > CH3CH2CH3
    • D) CH3CH2CH2OH > CH3CH2CH3 > CH3CH2OCH3

    Answer: CH3CH2CH2OH > CH3CH2OCH3 > CH3CH2CH3

    Explanation: CH3CH2CH2OH has the highest boiling point due to hydrogen bonding, followed by CH3CH2OCH3 (dipole-dipole interactions), and then CH3CH2CH3 (London forces).
