A C7H9N base reacts with sodium nitrite and hydrochloric acid at 0°C, giving a clear solution. On heating with KCN and Cu2(CN)2 a gas evolves, and continued heating with conc. HCl yields a C8H8O4 crystalline acid. Heating this acid with aqueous KMnO4 produces a C8H6O4 product, which dehydrates on strong heating to give a crystalline C8H4O3 com pound. What is the C7H9N base?
- a)Benzylamine
- b)N-methylaniline
- c)para-toluidine (the toluidines are aminotoluenes)
- d)ortho-toluidine
Correct answer is option 'D'. Can you explain this answer?

Answer:
To solve this question, we need to analyze the given reactions and identify the base C7H9N. Let's break down the reactions step by step:
Reactants:
- C7H9N base
- Sodium nitrite (NaNO2)
- Hydrochloric acid (HCl)
Reaction 1:
- Reactants: C7H9N + NaNO2 + HCl
- Product: Clear solution
This reaction is a diazotization reaction, which is commonly used to convert primary aromatic amines into diazonium salts. The clear solution indicates the formation of a diazonium salt.
Reaction 2:
- Reactants: Diazonium salt + KCN + Cu2(CN)2
- Product: Evolution of gas
In this reaction, the diazonium salt reacts with KCN and Cu2(CN)2 to form an aryl cyanide compound. The evolution of gas suggests the release of nitrogen gas.
Reaction 3:
- Reactants: Aryl cyanide compound + conc. HCl
- Product: C8H8O4 crystalline acid
In this reaction, the aryl cyanide compound reacts with concentrated HCl to form a C8H8O4 crystalline acid. The reaction likely involves hydrolysis of the cyanide group.
Reaction 4:
- Reactants: C8H8O4 crystalline acid + aqueous KMnO4
- Product: C8H6O4
In this reaction, the C8H8O4 crystalline acid reacts with aqueous KMnO4 to form a C8H6O4 product. The reaction likely involves oxidation of the acid.
Reaction 5:
- Reactants: C8H6O4 + strong heating
- Product: Crystalline C8H4O3 compound
In the final step, the C8H6O4 product undergoes dehydration on strong heating to form a crystalline C8H4O3 compound.
Conclusion:
Based on the given reactions, the C7H9N base can be identified as ortho-toluidine (option D).
