Which is more acidic Ortho chlorobenzoic acid or para chlorobenzoic acid?

Which is more acidic Ortho chlorobenzoic acid or para 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 p-fluorobenzoic acid is weaker acid than p-chlorobenzoic acid?

Fluorine is more electronegative than chlorine even then p-fluorobenzoic acid is a weaker acid than p-chlorobenzoic acid. Explain. -effect which outweighs the +R-effect. Consequently, p-fluorobenzoic acid is a weaker acid than p-chlorobenzoic acid.

Which has higher acidity between P methylbenzoic acid and p-chlorobenzoic acid?

HOPE THIS HELPS!!!! The pKa values are 4.21 (benzoic acid) and 4.38 (p-methylbenzoic acid), in other words, the former is slightly more acidic than the latter.

Which is more acidic para methyl benzoic acid or para chloro phenol?

Benzoic acid is more acidic than p-chloro phenol . It is benzoic acid which is more acidic of the two. In P- chloro phenol the electron withdawing chloro group would also tend to polarise the O-H bond of hydroxyl group..

Why phenol is stronger acid than ethanol?

Hint: Phenol loses its hydrogen ion to form the phenoxide ion which resonates and stabilizes itself and this loss of electrons makes the phenol more acidic than alcohol for example ethanol.

Why ortho methyl benzoic acid is more acidic than para fluoro benzoic acid?

Can you please explain me why Ortho methyle benzoic acid is more acidic than para fluro 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. Therefore, ortho methyl benzoic acid is more acidic than para fluoro benzoic acid.

Why is fluorine more acidic than chlorine?

Because the inductive effect depends on electronegativity, fluorine substituents have a more pronounced pKa-lowered effect than chlorine substituents.

Which is more acidic meta nitrobenzoic acid or para nitrobenzoic acid?

When both acids donate their proton from -COOH group then p-nitrobenzoate is more stabilized due to -M effect of nitro group than m-nitribenzoate because -M group more deactivates the ring / decreases charge than -I group. Thus, p-nitrobenzoic acid is more acidic than m-nitrobenzoic acid.

Why is meta methyl benzoic acid more acidic than para methyl benzoic acid?

The methyl group at ortho & para-position(4-position) destabilises Negative charge of corresponding Carboxylate ion both +I (Inductive ERG)) as well as by +H (hyperconjugation). Hence m-isomer is more acidic than para-isomer.

Why are ortho and para Nitrophenols more acidic than phenol?

The presence of this group in the ortho or para position decreases the electron density in the O? H bond. As a result, it is easier to lose a proton. Hence, ortho and para nitrophenols are stronger acids than phenol.

Why are phenols weaker acids than carboxylic acids?

The carboxylate ion formed is stabilized through resonance by effective delocalization of the negative charge. Therefore, the carboxylate ion exhibits higher stability in comparison to phenoxide ion. Hence, the carboxylic acids are more acidic than phenols.

Why Ortho nitrobenzoic acid is more acidic than para nitro benzoic acid?

ortho nitro benzoic acid is more acidic than para nitro benzoic acid due to the ortho effect. This makes the – COOH group go out of the plane of the benzene ring and looses the proton readily compared to para nitro benzoic acid which exihibits intermolecular hydrogen bonding.

What is the difference between Meta-chlorobenzoic acid and para-chloro acid?

Meta-chlorobenzoic acid is around 1.05 times more acidic than para-chlorobenzoic acid. In m-chlorobenzoic acid, the electronegative chlorine atom pulls some of the electron density towards itself.

Why is benzoic acid more acidic than para benzoic?

Benzoic acid is more acidic then that of para benzoic acid it is because the chlorine group attached at para position have both minus I effect and plus R effect.

Why is m-chlorobenzoic acid a stronger acid than chlorobenzene?

The chlorobenzoate ion is stabilised by the electron-withdrawing group. In m-chlorobenzoate ion, the electron-withdrawing chlorine atom is nearer to the carboxylate group, hence, the stronger electron-withdrawing effect. It’s more easily for m-chlorobenzoic acid to donate proton. So, it’s a stronger acid.

Why is p-hydroxybenzoic acid weak in meta position?

For the same reason that p-hydroxybenzoic acid is weaker than m-hydroxybenzoic acid: resonance electron donation in the para position destabilizes the conjugate base of the acid. That’s not possible in the meta position. Quora User’s answer to How does OH act as an electron withdrawing group?
