    Answer: The given compounds are arranged according to decreasing boiling point as CH_{3}OH > CH_{3}Cl > CH_{4}.

    Explanation:

    The temperature at which vapor pressure of a substance becomes equal to the atmospheric pressure is called boiling point.

    Stronger is the intermolecular forces present the atoms of a molecule more heat will be required by it to break the bond between its atoms. Hence, more will the boiling point of the molecule.

    In CH_{3}OH (methanol), there is hydrogen bonding present which is a stronger force. So, it will have highest boiling point as compared to CH_{3}Cl and CH_{4}.

    In CH_{3}Cl (chloroform), there is more electronegative atom attached (Cl) is attached to less electronegative atom (C and H). So, electrons are more pulled towards the chlorine atom. So, boiling point of  CH_{3}Cl is more than methane (CH_{4}).

    Thus, we can conclude that given compounds are arranged according to decreasing boiling point as CH_{3}OH > CH_{3}Cl > CH_{4}.
