How do you make M nitrobenzoic acid?
m-Nitrobenzoic acid can be prepared by the nitration of benzoic acid by means of nitric acid,1 a mixture of nitric and sulfuric acids,2 or mixtures of nitrates and sulfuric acid;3 all these methods lead to the production of a mixture containing principally the m-nitrobenzoic acid with a smaller proportion of the ortho …
How is benzoic acid converted to M nitrobenzoic acid?
Answer : When benzoic acid reacted with nitrating mixture it forms m- nitrobenzoic acid further it treated with SOCl2 it chlorinate the acidic COOH group. And reacting with NaBH4 further it get converted into m-nitroenzyl alcohol.
What is the formula of methyl benzoate?
C8H8O2
Methyl benzoate/Formula
What is the mechanism for the nitration of methyl benzoate?
Nitric and sulfuric acid react to form the nitronium ion electrophile. Nucleophilic π electrons attack the nitronium ion giving methyl 3-nitrobenzoate. in the aromatic region and one singlet upfield.
Why nitration of benzoic acid gives M nitrobenzoic acid?
That is because the group “-COOH” present in benzoic acid is electron-withdrawal, thus it is meta-directing. Because of this the electrophilic substitution reaction happens in the benzoic acid meta position. Hence, nitration of benzoic acid gives meta nitrobenzoic acid.
Which is the solvent used to dissolve meta nitrobenzoic acid?
The solvents used were toluene, acetone, methanol, water, 0.1 M HCl and 0.1 M NaOH. The compound was most soluble in acetone, methanol and NaOH.
How will you bring about the following conversions benzene to M Nitroacetophenone?
Answer : After frieadal craft acylation of benzene it will convert into acyl benzene. And further treating with nitrating mixture it forms m-nitroaceto phenone .
How is benzoic acid converted to benzamide?
Benzoic acid reacts with ammonia to give ammonium benzoate, which on heating gives benzamide.

Why is methyl M Nitrobenzoate formed in this reaction instead?
Why is methyl 3-nitrobenzoate formed in this reaction instead of the ortho or para isomers? Because methyl benzoate is a electron withdrawing unit and a meta director. The reaction generates a lot of heat, to much and it will affect the yeild of the product. Why are meta-directors deactivating?
How aniline is nitrated?
In case of nitration in aniline, the Nitric Acid protonates the aniline to form the Anilinium ion. Now since the nitrogen atom has no lone pair to conjugate, it has no mesomeric effect on the ring, the but as nitrogen is now protonated, it has a high negative inductive effect.
How is m-Nitrobenzoic acid filtered in an organic syntheses?
After the solution has cooled to room temperature, the m-nitrobenzoic acid is filtered off by means of suction. This crude acid when dry weighs 150–160 g. ( 90–96 per cent of the theoretical amount). It has a light brownish color, melts at 140°, and should be completely soluble in ether, thus showing the absence of salts.
What is the molecular formula for methyl 3-nitrobenzoate?
Methyl 3-nitrobenzoate PubChem CID 69260 Structure Find Similar Structures Molecular Formula C8H7NO4 Synonyms Methyl 3-nitrobenzoate 618-95-1 3-Nitrob Molecular Weight 181.15
How to synthesize nitrobenzoate with sodium hydroxide?
1. Procedure In a 2-l. round-bottomed flask fitted with a reflux condenser are placed a solution of 80 g. (2 moles) of sodium hydroxide in 320 cc. of water (Note 1) and 181 g. (1 mole) of methyl m-nitrobenzoate (not recrystallized, p. 372 ).
What is the mechanism of the nitrification reaction?
Mechanism of nitrification reaction: propose a synthetic pathway for synthesis of p-nitrobenzoic acid and m-nitrobenzoic acid if you are starting from benzene. How about these? I. The Nitration Mechanism
