    Which of die following represents the correct order of the acidity in the given compounds?         [AIPMT (S) 2007]

    A)  \[C{{H}_{3}}COOH>BrC{{H}_{2}}COOH>ClC{{H}_{2}}COOH\] \[>FC{{H}_{2}}COOH\]

    B)       \[FC{{H}_{2}}COOH>C{{H}_{3}}COOH>BrC{{H}_{2}}COOH\]\[>ClC{{H}_{2}}COOH\]

    C)       \[BrC{{H}_{2}}COOH>CIC{{H}_{2}}COOH>FC{{H}_{2}}COOH\]\[>C{{H}_{3}}COOH\]

    D)       \[FC{{H}_{2}}COOH>ClC{{H}_{2}}COOH>BrC{{H}_{2}}COOH\]\[>C{{H}_{3}}COOH\]

    Correct Answer: D

    Solution :

    The acidity of halogenated acid increases almost proportionately with the increase in electronegativity of the halogen present. So, the correct order is:
    FCH2COOH > ClCH2COOH> BrCH2COOH> CH3COOH
