    A compound is known to have either the structure H2NCH2CH2NH2 or H2NCH2COOH.
    Which of the following tests would best distinguish between the two compounds?
    A Reaction with concentrated aqueous sodium hydroxide.
    B Reaction with nitrous acid.
    C Reaction with aqueous sodium hydrogencarbonate.
    D Reaction with ethanoyl chloride.

    THE ANSWER IS C BUT I PUT D I REALLY DO NOT UNDERSTAND WHAT IS GOING ON

    ANY HELP WOULD BE APPRECIATED

    THANK YOU

    One of your compounds is an organic acid. They react with hydrogencarbonates to produce effervescence, t'other doesn't.
