Question

The increasing order of acidity of the following compounds based on pKa values: BrCH$_2$COOH, ClCH$_2$COOH, FCH$_2$COOH, HCOOH

• (D) $<$ (A) $<$ (B) $<$ (C)
• (A) $<$ (D) $<$ (C) $<$ (B)
• (B) $<$ (A) $<$ (D) $<$ (C)
• (C) $<$ (B) $<$ (D) $<$ (A)

Answer 1

The Correct Option is A

The acidity of carboxylic acids depends on the electron-withdrawing effects of substituents. More electronegative substituents increase the acidity.
