Read the passage given below and answer the following questions:A mix...
Explanation:
The passage describes the separation of a mixture of two aromatic compounds (A) and (B) using chloroform and aqueous KOH solution. When compound (A) is heated with alcoholic solution of KOH, it produces a compound (C) with an unpleasant odor. The question asks why direct nitration of compound (A) is not feasible.
Reasons for direct nitration of compound (A) not being feasible:
1. Oxidation of aromatic compounds: Nitric acid can oxidize most aromatic compounds to give oxidation products along with only a small amount of nitrated products. This means that when compound (A) is treated with nitric acid, it may not exclusively undergo nitration, but can also undergo oxidation, leading to the formation of various oxidation products. Hence, the reaction cannot be stopped at the mononitration stage.
2. Mixture of nitroaniline isomers: Direct nitration of compound (A) may result in the formation of a mixture of o-, m-, and p-nitroaniline isomers. Nitration involves the substitution of a nitro (-NO2) group onto the aromatic ring. Depending on the position of substitution, different isomers can be formed. This is due to the presence of multiple reactive positions on the aromatic ring. Therefore, direct nitration of compound (A) would lead to a mixture of nitroaniline isomers, and not a single desired product.
3. Unpleasant odor: When compound (A) is heated with alcoholic solution of KOH, it produces compound (C) associated with an unpleasant odor. The presence of this odor suggests that compound (C) is likely to be an undesirable side product of nitration. This further supports the idea that direct nitration of compound (A) is not feasible.
Conclusion:
In summary, direct nitration of compound (A) is not feasible because nitric acid can oxidize most aromatic compounds, resulting in the formation of oxidation products along with a small amount of nitrated products. Additionally, nitration of compound (A) would lead to the formation of a mixture of nitroaniline isomers. The presence of an unpleasant odor associated with compound (C) produced from compound (A) further supports the idea that direct nitration is not a suitable method for obtaining desired products.
