Answer & Solution

Correct Answer

(D) FCH2CO2H>CH3CH2CHClCO2H>C6H5CO2H>CH3CO2H

Step-by-step Solution

Detailed explanation

Acidity is directly proportional to the -I,-M effect. The -I effect of the fluorine atom is higher than the chlorine atom. So, the FCH2CO2H has more acidity than the CH3CH2CHClCO2H. The benzoic acid has more acidic strength than the acetic acid because phenyl group show the -I…
