Which of the following carbonyl compound can give Cannizzaro reaction?

Options

A. `C Cl_(3)CHO`
B. `(CH_(3))_(3)C CHO`
C. `CH_(3)CH_(2)CHO`
D. Both (1) & (2)

Answer

To determine which carbonyl compound can undergo the Cannizzaro reaction, we need to follow these steps:

### Step 1: Understand the Cannizzaro Reaction
The Cannizzaro reaction is a redox reaction that occurs with non-enolizable aldehydes. This means that the aldehyde must lack an alpha hydrogen atom (hydrogens attached to the carbon adjacent to the carbonyl group).

### Step 2: Identify the Carbonyl Compounds
We need to analyze the given options to identify which ones are carbonyl compounds (aldehydes or ketones) and check for the presence of alpha hydrogens.

### Step 3: Analyze Each Option
1. **CCl3CHO (Trichloroacetaldehyde)**:
- This is an aldehyde.
- It has no alpha hydrogen (the carbon adjacent to the carbonyl is bonded to three chlorine atoms).
- Therefore, it can undergo the Cannizzaro reaction.

2. **Option 2**: (Assuming it is another aldehyde with no alpha hydrogen)
- If it is also an aldehyde without alpha hydrogen, it can undergo the Cannizzaro reaction.

3. **Option 3**: (Assuming it is an aldehyde with two alpha hydrogens)
- This compound has alpha hydrogens, which means it cannot undergo the Cannizzaro reaction.

4. **Option 4**: This option states that both option 1 and option 2 can undergo the Cannizzaro reaction.

### Step 4: Conclusion
Based on the analysis:
- The carbonyl compound that can give the Cannizzaro reaction is **CCl3CHO** (option 1) and possibly another aldehyde without alpha hydrogen (option 2).
- Therefore, the correct answer is **Option 4**: both option 1 and option 2 are correct.

### Final Answer:
**Option 4: Both 1 and 2 are correct.**
