Why pKa of F - CH2 - COOH is lower than that of Cl - CH2 - COOH? – InterviewSolution

1.	Why pKa of F - CH2 - COOH is lower than that of Cl - CH2 - COOH?
Answer» In FCH₂ - COOH, tluorine is more electron withdrawing and has stronger ^-l effect than chlorine in CICH₂- COOH. So, FCH₂COOH is more acidic than CICH₂COOH hence its pK_a value is lesser than CICH₂COOH.
