Why is 4 nitrobenzoic acid a stronger acid compared to 4 methoxybenzoic acid?

Acidic strength increases if there is less electron density on a particular compound. And,as we know greater the electron density on the compound,lesser acidic it will be. Therefore,4 nitrobenzoic is stronger acid then benzoic acid and 4-methoxybenzoic is weaker acid then benzoic acid.

Why is 4 nitrobenzoic acid more acidic?

4-Nitrobenzoic acid is a stronger acid because the nitro group makes the aromatic ring unstable. 4-Nitrobenzoic acid is a stronger nod because the nitro group can produce nitric add.

Which nitrobenzoic acid is strongest?

o-nitrobenzoic acid
o-nitrobenzoic acid is the strongest acid among these. −NO2 group is a powerful electron withdrawing group and it has most effect when present at o-position. It is also known as o-effect.

Is benzoic acid or 4 methoxybenzoic acid more acidic?

-Since electron-donating groups decrease the acidic strength, $4 – $ methoxy benzoic acid is a weaker acid than benzoic acid. -Also, since electron-withdrawing groups increase the acid strength, therefore, both $4 – $nitrobenzoic acid and $3,4 – $ dinitrobenzoic acid are stronger acids than benzoic acid.

Which is more acidic benzoic acid or Nitrobenzoic?

Because the benzoic acid have a resonance effect. But the nitrobenzoic acid have a intermolecular bond. That’s why the nitrobenzoic acid is stronger than the benzoic acid. Nitro group is an electron withdrawing group which increases the acidity of the benzoic acid.

Why P-nitrobenzoic acid is stronger than M 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.

Is 2 methoxybenzoic acid water soluble?

3D Structure for HMDB0032604 (2-Methoxybenzoic acid)

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

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

Is nitrobenzoic acid acidic?

Nitrobenzoic acids are derivatives of benzoic acid. Two are commercially important. They are about ten times more acidic than the parent benzoic acid. Nitrobenzoic acid can be prepared through the oxidation of styrene in boiling nitric acid.

Which is most acidic 2 points 4-methoxy benzoic acid benzoic acid 4-nitrobenzoic acid phenol?

As 3, 4-dintrobenzoic acid contains two nitro groups, it is a slightly stronger acid than 4-nitrobenzoic acid. Hence, the strength of the given acid increase as: 4-Methoxy benzoic acid < Benzoic acid < 4-Nitrobenzoic acid < 3, 4-Dinitrobenzoic acid.

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

So the acidity trend is para methyl benzoic acid < benzoic acid < para nitrobenzoic acid.
