How do you make para nitrobenzoic acid from benzene?

(iii) To form p-nitrobenzoic acid, first, perform Friedel Craft alkylation to get toluene and then form p-nitrotoluene by nitration. Minor products can be eliminated by filtration. Oxidation of the compound gives us p-nitrobenzoic acid.

Which synthesis will yield m-nitrobenzoic acid?

nitration of methyl benzoate
m-Nitrobenzoic acid is obtained in a higher yield by nitration of methyl benzoate (p.

What happens when 2 Bromo 4-nitrotoluene reacts with tin and hydrochloric acid?

43. 4-nitrotoluene is treated with bromine to get compound ‘P’ which is reduced with Sn and HCl to get compound ‘Q’. ‘Q’ is diazotised and the product is treated with phosphinic acid to get compound ‘R’. 2-bromo-4-hydroxybenzoic acid.

How do you make p-nitrotoluene?

The mixture of p-nitrotoluene and o-nitrotoluene can be separated by fractional distillation. Thus, benzene is converted p-nitrotoluene by converting benzene to toluene then toluene to a mixture of o-nitrotoluene and p-nitrotoluene and then separating the mixture by fractional distillation to get p-nitrotoluene.

How is benzoic acid converted into 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.

How is benzocaine synthesized industrially from P-nitrobenzoic acid?

Chemistry. Benzocaine is the ethyl ester of p-aminobenzoic acid (PABA). It can be prepared from PABA and ethanol by Fischer esterification or via the reduction of ethyl p-nitrobenzoate.

How do you make nitrobenzoic acid?

Production. 4-Nitrobenzoic acid is prepared by oxidation of 4-nitrotoluene using oxygen or dichromate as oxidants. Alternatively, it has been prepared by nitration of polystyrene followed by oxidation of the alkyl substituent.

Why is P-nitrobenzoic acid more acidic 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.

What happens when nitrobenzene is treated with Sn and HCl?

When nitrobenzene is reduced with a metal and acid (Sn/HCl, Zn/HCl etc.), aniline is obtained.
