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 Ortho methyl benzoic acid or para methyl 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.

Which benzoic acid is most acidic?

O-nitro benzoic acid is most acidic due to ortho effect.

Which one is more acidic benzoic acid or ortho methyl benzoic acid?

Note: The acidic strength of m-toluic acid is more than p-toluic acid but less than benzoic acid, actually o-toluic acid also should have less acidic strength than benzoic acid due to presence of the electron withdrawing group. But due to ortho effect it’s acidic strength is higher than benzoic acid.

Which is more acidic methyl benzene?

As a result, its IUPAC designation is methylbenzene. group, it is more acidic than toluene.

Which group of GP is more acidic?

In other words, a group in the ortho position always increases the acid strength of an aromatic acid. Out of ortho, meta and para substituted benzoic acids, the ortho compound will be the strongest acid, although there is no satisfactory explanation for this.

What is ortho effect in benzoic acid?

The Ortho effect is the process in which ortho contained benzoic acids are reasonably stronger than benzoic acid. It doesn’t matter whether the substitute is electron-withdrawing or electron releasing. In simple words, a group in the ortho position constantly boosts the acid strength of an aromatic acid.

Which group makes benzoic acid more acidic?

Electron-withdrawing groups deactivate the benzene ring to electrophilic attack and make benzoic acids more acidic.

Why is 2 chloroacetic acid a more stronger acid than acetic acid?

Due to the inductive effect of the chlorine atom the electron density is reduced over the already weakened O-H bond in the carboxylic moiety (due to the presence of alpha carbonyl group) which in turn make it a stronger acid than acetic acid as the ease of releasing the hydrogen to the base is increased.

Why is chloroacetic acid more acidic?

Question: Why chloroacetic acid is more acidic than acetic acid? Answer: Chloroacetic acid is stronger, because it contains (more electronegative) chlorine atoms in the place of (less electronegative) hydrogen atoms.

What is the difference between benzoic acid and 2-methyl benzoic acid?

2-Methyl Benzoic acid (or o-toluic acid) is stronger than either because steric hindrance results in the carboxyl group being out of the plane of the aromatic ring. [Ortho effect- o-toluic acid is even stronger than benzoic acid.]

Why is o-Toluic acid a stronger acid than benzoic acid?

It is this stabilization provided by the methyl group that makes o-toluic acid a stronger acid (pKa=3.91) than benzoic acid (pKa=4.19). Note: As pointed out by both @Mithoron and @GaurangTandon, this answer does not explain why p -toluic acid is a weaker acid than o -toluic acid or benzoic acid.

What are the pKa values of benzoic and methylbenzoic acids?

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.

What is the molecular weight of 4-methylbenzoic acid?
