Question

Quizplus · Accepted Answer

The best method for preparing m-nitrobenzoic acid involves the following sequence of reactions:
1. Chlorination of benzene to form chlorobenzene using CHCl3/AlCl3
2. Nitration of chlorobenzene with HNO3/H2SO4 to form m-nitrochlorobenzene
3. Separation of isomers by fractional distillation
4. Oxidation of m-nitrochlorobenzene with KMnO4 in acidic medium to form m-nitrobenzoic acid
5. Conversion of the carboxylic acid group to a more reactive acid chloride using SOCl2
6. Hydrolysis of the acid chloride with water to form m-nitrobenzoic acid. 
Therefore, option C is the correct choice as it follows the above sequence of reactions.
