Question

In the following pair which is more acidic?

$\text{C}{\text{H}}_{\text{2}}\text{FC}{\text{H}}_{\text{2}}\text{C}{\text{O}}_{\text{2}}\text{H,}\text{C}{\text{H}}_{\text{3}}\text{CHMFCHC}{\text{O}}_{\text{2}}\text{H}$

Answer 1

Since inductive effect is dependent on distance, so when $F$ is near to acid group, then it is more acids, than when $F$ is far from acid group.

Acid = $C{H}_{3}CHMFCHC{O}_{2}H>C{H}_{2}FC{H}_{2}COOH$
