MCQ
Which is the strongest acid ($pk_a$ value is given)?
  • ✓
    $HCOOH\, [3.77]$
  • B
    $C_6H_5COOH\, [4.22]$
  • C
    $CH_3COOH\, [4.7]$
  • D
    $CH_3CH_2COOH \,[4.88]$
✓

Answer

Correct option: A.
$HCOOH\, [3.77]$
a
\because Strength of acid $ \propto \frac{1}{{p{k_a}}}$
\therefore Formic acid will be the strongest acid.
