Question

Arrange the following acids in order of their increasing acidity.

$A < B < C < D$

$B < C < A < D$

$C < B < D < A$

$C < D < B < A$

Answer

$C < D < B < A$

Explanation

Solution

Electron-donating substituents tend to decrease while electron-withdrawing
substituents tend to increase the acidic strength of substituted benzoic acids relative to benzoic adds. However, due to ortho-effect, $o$ -nitro-benzoic add is the stronger add then $p$ -nitrobenzoic add.
