Why P Fluorobenzoic acid is weaker than P-chlorobenzoic acid?
Fluorine is more electronegative than chlorine, so logically, fluorobenzoic acid should be a stronger acid than chlorobenzoic acid. Hence, p-fluorobenzoic acid is a weaker acid than p-chlorobenzoic acid.
Why ortho methyl benzoic acid is more acidic than para fluoro benzoic acid?
Answer: In the case of O-methyl benzoic acid, the methyl group attached to the benzene ring is stabilized the conjugate base formed. But in case of Para fluoro benzoic acid, there is no such stabilization is not seen. Therefore, ortho methyl benzoic acid is more acidic than para fluoro benzoic acid.

Which is more acidic Fluorobenzoic acid or chlorine?
(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.
Which is more acidic chlorobenzoic acid or chlorobenzoic acid?
Meta-chlorobenzoic acid is around 1.05 times more acidic than para-chlorobenzoic acid.
Is 2 methyl benzoic acid or benzoic acid more acidic?
Benzoic acid is more acidic than 2- methyl benzoic acid because CH3 has +I effect and hyperconjugative effect that destabilizes the carboxylate ion.

Which is more acidic p-fluorobenzoic acid or p-chlorobenzoic acid?
Fluorine is more electronegative than chlorine but p-fluorobenzoic acid is a weaker acid than p-chlorobenzoic acid. Both fluorine and chlorine are involved in -I effect as well as +M effect (due to presence of lone electron paris) with the benzene ring.
