Question

Choose the correct statement regarding acidic character of acetic acid, $C{H}_{3}COOH$ and peroxyacetic acid, $C{H}_{3}COOOH$

• A. Peroxyacetic acid is stronger acid than acetic acid since the former has one extra oxyge, an electronegative element
• B. Peroxyacetic acid is stronger than acetic acid because its conjugate base is a weaker base than acetate
• C. Peroxyacetic acid is weaker than acetic acid because its conjugate base is less stable than that of acetate ion
• D. Both are equally strong

Answer 1

The correct option is C

Peroxyacetic acid is weaker than acetic acid because its conjugate base is less stable than that of acetate ion
