Fluorine is more electronegative than chlorine but p-fluorobenzoic acid is a weaker acid than p-chlorobenzoic acid. Explain.

(A) Although fluorine is more electronegative than chlorine, yet p-fluorobenzoic acid is a weaker acid than p-chlorobenzoic acid. (R) Due to matching sizes of 2p orbitals of F and carbon, F has a stronger +R effect than Cl.

Assertion : Although fluorine is more electronegative than chlorine, p-chlorobenzoic acid is a stronger acid than p-fluorobenzoic acid. Reason : Due to mathcing size of 2p-orbitals of F and C, F has stronger +R effect than Cl.
