The order of acidity of following acids is:

\[\begin{matrix} C{{H}_{3}}-C{{F}_{2}}-COOH \\ I \\ \end{matrix}\] \[\begin{matrix} C{{H}_{3}}\underset{Br}{\mathop{\underset{|}{\mathop{-CH}}\,}}\,-COOH \\ II \\ \end{matrix}\]

\[\begin{matrix} C{{H}_{3}}-\underset{Br}{\overset{Br}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-COOH \\ III \\ \end{matrix}\] \[\begin{matrix} C{{F}_{3}}-COOH \\ IV \\ \end{matrix}\]

A) I > II > III > IV

B) IV > III > II > I

C) IV > I > III > II

D) IV > III > I > II

Correct Answer: C

The order of acidity of following acids is:
\[\begin{matrix} C{{H}_{3}}-C{{F}_{2}}-COOH \\ I \\ \end{matrix}\]	\[\begin{matrix} C{{H}_{3}}\underset{Br}{\mathop{\underset{\|}{\mathop{-CH}}\,}}\,-COOH \\ II \\ \end{matrix}\]
\[\begin{matrix} C{{H}_{3}}-\underset{Br}{\overset{Br}{\mathop{\underset{\|}{\overset{\|}{\mathop{C}}}\,}}}\,-COOH \\ III \\ \end{matrix}\]	\[\begin{matrix} C{{F}_{3}}-COOH \\ IV \\ \end{matrix}\]
