Is 3-nitrobenzoic acid a strong acid?
With a pKa of 3.47, 3-nitrobenzoic acid is about ten times more acidic than benzoic acid. The conjugate base of benzoic acid is stabilised by the presence of the electron withdrawing nitro group which explains its increased acidity in comparison to unsubstituted benzoic acid.
Is 3-nitrobenzoic acid an acid or base?
The compound was identified as 3-nitrobenzoic acid by a combination of tests. The compound was an organic compound with a melting point of 131-141°C, which was found to be most soluble in polar organic solvents.
How do you make 3-nitrobenzoic acid?
1,519,602 discloses a process for the preparation of 3-nitrobenzoic acid by nitration of benzoic acid with nitric acid in sulfuric acid below 10° C. over about 2 hours. The mixture is then warmed to 40° C.
What is the structural formula of 3-nitrobenzoic acid?
C7H5NO43-Nitrobenzoic acid / Formula
Why is O-nitrobenzoic acid more acidic than m-nitrobenzoic acid?
Hence, nitro group on ortho position has higher inductive effect compared to the nitro group on para position. Therefore, more liberation of H+ is causes the acidity of a compound. Hence, , o-nitrobenzoic acid is more acidic compared to p-nitrobenzoic acid.
Why para nitro benzoic acid is more acidic than meta 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 O nitrobenzoic acid more acidic than m-nitrobenzoic acid?
How do you make 2 nitrobenzoic acid?
2-Nitrobenzoic acid is an organic compound with the formula C6H4(NO2)CO2H. It is prepared by oxidation of 2-nitrotoluene with nitric acid.
How do we go from toluene to nitrobenzoic acid?
To convert toluene to 3-nitrobenzoic acid, oxidation is first performed on the toluene by using alkaline KMnO4 K M n O 4 . This is followed by nitration, which is an electrophilic substitution reaction.
What is the boiling point of 3 nitrobenzoic acid?

Which is more acidic nitrobenzoic acid or hydroxybenzoic acid?
The -M effect of NO2 will stabilize the electron density of conjugate anoin (base). From that logic also, since NO2 is ewg and OH is edg, o-nitrobenzoic acid is more acidic than o-hydroxybenzoic acid.
What is 3-nitrobenzoic acid?
3-Nitrobenzoic acid is a precursor to 3-aminobenzoic acid, which in turn is used to prepare some dyes. It can be prepared by nitration of benzoic acid.
