Which is more acidic benzoic acid or p methyl benzoic acid?

Methyl groups are weak donors and so p-methylbenzoic acid is weaker than benzoic acid. Chlorine is a weak electron donor (by resonance) and hence p-chlorobenzoic acid is slightly stronger than benzoic acid.

Which acid is a weaker acid than benzoic acid 1 point p methyl benzoic acid p-chlorobenzoic acid p nitro benzoic acid O chlorobenzoic acid?

– Consequently, p-fluorobenzoic acid is a weaker acid than p-chlorobenzoic acid.

Which is more acidic p methyl benzoic acid?

So p methyl benzoic acid is more acidic than p methoxy benzoic acid. 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.

Why o-toluic acid is stronger than benzoic acid?

Both inductively and through resonance (see the hyperconjugated resonance structure below on the right) the methyl group will stabilize this resonance structure. 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).

Why o chlorobenzoic acid is stronger than its P isomer?

All the oxygen-containing groups exhibit base-strengthening effects relative to benzoic acid itself and a11 but hydroxyl cause the ortho acids to be stronger bases than their para isomers. This can be attributed to hydrogen bonding in the conjugate acid, viz.

Which of the following acid is most acidic * 1 point P methyl benzoic acid p nitrobenzoic acid benzoic acid p methoxy benzoic acid?

The correct answer is option 2. 2-Nitrobenzoic acid is the most acid compound in the above diagram. It is also known as o-Nitrobenzoic acid.

Is methyl benzene acidic?

A solution of HCl in methylbenzene does not contain hydrogen ions, so it is not acidic.

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 ortho effect in benzoic acid?

Ortho Effect- The ortho substituted benzoic acid (whether the substituent is electron withdrawing or releasing is comparatively stronger acid than the para and meta isomers. This effect is called ortho effect. It occurs due to the steric effect ,carboxylate anion due to nearness of the substituent is stabilized.
