Which of the following compound reacts with chlorofom and a base of form phenyl isocyanide?

Options

A. Phenol
B. Aniline
C. Benzene
D. Nitro benzene

Answer

To determine which compound reacts with chloroform (CHCl3) and a base to form phenyl isocyanide, we can follow these steps:

### Step 1: Identify the Reaction
The reaction in question involves chloroform and a base. Specifically, we are looking for a compound that can react with chloroform in the presence of a strong base to yield phenyl isocyanide.

### Step 2: Recall the Specific Reaction
From organic chemistry, we know that aniline (C6H5NH2) reacts with chloroform and a strong base (like KOH) to produce phenyl isocyanide. The reaction can be summarized as follows:

\[ \text{Aniline} + \text{CHCl}_3 + 3 \text{KOH} \rightarrow \text{Phenyl isocyanide} + 3 \text{KCl} + 3 \text{H}_2\text{O} \]

### Step 3: Write the Balanced Equation
The balanced equation for the reaction is:

\[ \text{C}_6\text{H}_5\text{NH}_2 + \text{CHCl}_3 + 3 \text{KOH} \rightarrow \text{C}_6\text{H}_5\text{N} \equiv \text{C} + 3 \text{KCl} + 3 \text{H}_2\text{O} \]

### Step 4: Identify the Correct Compound
Given the options, we need to identify which one is aniline. Aniline is a primary amine with the formula C6H5NH2. If one of the options is aniline, then it is the correct answer.

### Conclusion
The compound that reacts with chloroform and a base to form phenyl isocyanide is **aniline**.
