Question

Which one of the following is strongest acid?

Options
  • A

    FCH COOH

  • B

    CH3COOH

  • C

    CICH COOH

  • D

    C6H5CH,COOH

Explanation

Electronegativity increases the acidity by increasing the ionic character of O-H. Electronegativity decreases in the order F > Cl > Br, and hence the acidic effect also decreases in the same order.

Here and overall, fluorine is the most electronegative element. Thus, it is most acidic.
