The acidity of halogenated acid increases with increase in electronegativity of the halogen present. So, the correct order is order is \(\mathrm{F}>\mathrm{Ce}>\mathrm{Br}\) \(F C H_{2} C O O H>C l C H_{2} C O O H>B r C H_{2} C O O H>C H_{3} C O O H\)

Which of the following reagents may be used to distinguish between phenol and benzoic acid ?
28172
The strongest acid amongst the following compounds is :
1 \(CH_3COOH\)
2 \(HCOOH\)
3 \(CH_3CH_2CH(Cl)CO_2H\)
4 \(ClCH_2CH_2CH_2COOH\)
Explanation:
The electron withdrawing \(( - I)\) group - \(C l\) withdraws electrons from \(O-H\) bond and thus the cleavage of the \(O-H\) bond releasing hydrogen as \(H^{\prime}\)
