Chloroform reacts with which of these to form a hypnotic?

Options

A. Ethanal
B. Propanone
C. Propanoic acid
D. Ethyl alcohol

Answer

To determine which compound chloroform reacts with to form a hypnotic, we need to analyze the options provided and understand the reaction involved.

### Step-by-Step Solution:

1. **Understanding the Question**:
- We need to identify which compound reacts with chloroform (CHCl3) to produce a hypnotic agent. A hypnotic agent is a substance that induces sleep.

2. **Identifying the Options**:
- The options given are:
- A) Ethanol
- B) Propanol
- C) Propanoic acid
- D) Ethyl alcohol

3. **Recalling Relevant Reactions**:
- Chloroform is known to react with acetone (which is propanone) in the presence of a strong base like potassium hydroxide (KOH) to produce a hypnotic compound known as chloretone.

4. **Identifying the Correct Compound**:
- Among the options, we need to find which one corresponds to acetone.
- Acetone is chemically known as propanone (C3H6O), which is not explicitly listed in the options but is related to propanol.

5. **Analyzing the Options**:
- Ethanol (C2H5OH) and ethyl alcohol are the same and do not react with chloroform to produce a hypnotic.
- Propanol (C3H7OH) does not react with chloroform to yield a hypnotic.
- Propanoic acid (C2H5COOH) also does not lead to the formation of a hypnotic when reacted with chloroform.

6. **Conclusion**:
- The hypnotic formed from chloroform is actually from its reaction with acetone (propanone). Since propanone is not listed, we conclude that the closest related option is **propanol**, but it does not directly yield a hypnotic. However, the question implies a misunderstanding in the options provided.
- The correct answer based on the reaction is **propanone (acetone)**, which is not listed, but if we consider propanol as a related compound, it is the closest option.

### Final Answer:
- The answer is **Propanone (though not listed, it is the correct reactant)**.
