Wired Faculty App

Which of the following represents the correct order of the acidity in the given compounds?

  • H3CCOOH > BrCH2COOH > ClCH2COOH > FCH2COOH

  • FCH2COOH > CH3COOH >BrCH2COOH > ClCH2COOH

  • BrCH2COOH > ClCH2COOH > FCH2COOH >CH3COOH

  • FCH2COOH > ClCH2COOH >BrCH2COOH > CH3COOH

Solution

D.

FCH2COOH > ClCH2COOH >BrCH2COOH > CH3COOH

The acidity of halogenated acid increases proportionately with the increase in electronegativity of the halogen present. So, the correct order is:
FCH2COOH > ClCH2COOH >BrCH2COOH > CH3COOH
