Explain the following statement. Although $2\text{-}$ methoxy acetic acid $\left({\text{CH}}_{\text{3}}{\text{OCH}}_{\text{2}}\text{COOH}\right)$ is a stronger acid than acetic acid $\left({\text{CH}}_{\text{3}}\text{COOH}\right)$, $p\text{-}$ methoxy benzoic acid $\left({\text{CH}}_{\text{3}}{\text{OC}}_{\text{6}}{\text{H}}_{\text{4}}\text{COOH}\right)$ is a weaker acid than benzoic acid $\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\text{COOH}\right)$.
