The correct Answer is:
To solve the question regarding the reaction of chloroform with alcoholic KOH and p-toluidine, we will follow these steps: ### Step 1: Identify the Reactants - **Chloroform (CHCl3)**: A halogenated hydrocarbon. - **Alcoholic KOH**: A strong base that can deprotonate compounds. - **p-Toluidine**: An aromatic amine with the structure of a benzene ring with an amino group (-NH2) at the para position relative to a methyl group (-CH3). ### Step 2: Understand the Reaction Mechanism The reaction involves the formation of isocyanide (also known as carbanamine) through a series of steps: 1. **Deprotonation**: The alcoholic KOH will deprotonate the amino group of p-toluidine, making it a stronger nucleophile. 2. **Formation of Isocyanide**: The deprotonated p-toluidine will then react with chloroform in the presence of KOH. Chloroform acts as a source of carbon and halide ions. The nucleophilic amine attacks the carbon atom in chloroform, leading to the formation of isocyanide. ### Step 3: Write the Balanced Reaction The overall reaction can be summarized as: \[ \text{p-Toluidine} + \text{CHCl}_3 + \text{KOH} \rightarrow \text{Isocyanide} + 3 \text{HCl} + 3 \text{H}_2\text{O} \] ### Step 4: Identify the Product The main product formed from this reaction is **p-Tolyl isocyanide**. This compound is characterized by its foul smell and is used in the carbanamine test for primary amines. ### Conclusion The final product of the reaction of chloroform with alcoholic KOH and p-toluidine is **p-Tolyl isocyanide**. ---
