The correct increasing order acid strength of carboxylic acid is ……
(a) F – CH2 – COOH > I – CH2 – COOH > CI – CH2 – COOH > Br – CH2 – COOH
(b) Br – CH2 – COOH > F – CH2 COOH > I – CH2COOH > Cl – CH2 –COOH
(c) F – CH2 – COOH > CI – CH2 COOH > Br – CH2COOH > I – CH2 COOH
(d) Br – CH2 – COOH > CI – CH2 – COOH > I – CH2COOH > F – CH2COOH
