MCQ
Among the following acids which has the lowest $pKa$ value
- A$C{H_3}COOH$
- ✓$HCOOH$
- C${(C{H_3})_2}CH - COOH$
- D$C{H_3}C{H_2}COOH$
✓
Answer
Correct option: B.
$HCOOH$
b
(b)${K_a} \propto \frac{1}{{p{K_a}}}$; The value of ${K_a}$ is highest for $HCOOH$.
(b)${K_a} \propto \frac{1}{{p{K_a}}}$; The value of ${K_a}$ is highest for $HCOOH$.
