Which reaction takes place in synthesis of m-nitrobenzoic acid?
nitration reaction
The benzoic acid then undergoes a nitration reaction in presence of nitric acid and sulphuric acid to form m-nitrobenzoic acid.

How will you prepare m-nitrobenzoic acid from benzene?
The process is called esterification. (ii) One of the many possible ways to prepare m-nitrobenzoic acid is by first forming acetophenone by Friedel Craft acylation and then form nitroacetophenone by nitration of the compound. Oxidation of the compound gives us our desired product.
Which is more acidic Ortho nitrobenzoic acid or para nitrobenzoic acid?
The acidity of ortho-nitrobenzoic acid is more as compared with para-nitrobenzoic acid because of the “ortho effect”.
Why is p-nitrobenzoic acid more acidic than m-nitrobenzoic acid?
Explanation: 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..
Which of the following is the strongest acid 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.
Which is more acidic O-nitrobenzoic acid p-nitrobenzoic acid or m-nitrobenzoic acid?
The -R and -I effect is more pronounced at the ortho and para positions as compared to the meta position. Thus, p-nitrobenzoic acid is a stronger acid than m-nitrobenzoic acid. Hence, the correct order of acidic strength is o- nitrobenzoic acid > p-nitrobenzoic acid >m-nitrobenzoic acid> Benzoic acid.
How will you prepare the following compounds from benzene methyl benzoate?
(i) Methyl benzoate is the ester of benzene. It can easily be prepared after preparing benzoic acid. So, we can form benzoic acid by Friedel Craft alkylation and then form an ester, we can just oxidize the formed acid to get methyl benzoate. The process is called esterification.

How do you make 4-Nitrobenzoic acid?
4-Nitrobenzoic acid is produced commercially by the oxidation of 4-nitrotoluene with molecular oxygen. Oxidation with 15% nitric acid at 175 °C produces the acid in 88.5% yield.
What is the mobility of 3-nitrobenzoic acid in soil?
If released to soil, 3-nitrobenzoic acid is expected to have moderate mobility based upon an estimated Koc of 240.
