`2C_(6)H_(5)CHO overset(NaOH) to C_(6)H_(5)CH_(2)OH + C_(6)H_(5)COONa`
The similar reaction can take place with which of the following aldehyde?

Options

A. `CH_(3)CHO`
B. `CH_(3)CH_(2)CHO`
C. `(CH_(3))_(3)(C)CHO`
D. `CH_(3)CH_(2)CH_(2)CHO`

Answer

To solve the question, we need to identify which of the given aldehydes can undergo a similar reaction to the one shown with benzaldehyde (C₆H₅CHO) in the presence of NaOH. The reaction described is a Cannizzaro reaction, which occurs with aldehydes that do not have alpha-hydrogens.

### Step-by-Step Solution:

1. **Understanding the Cannizzaro Reaction**:
- The Cannizzaro reaction occurs with aldehydes that lack alpha-hydrogens. In this reaction, one molecule of the aldehyde is oxidized to a carboxylic acid (or its salt), while another molecule is reduced to an alcohol.

2. **Analyzing the Given Reaction**:
- The reaction given is:
\[ 2C_{6}H_{5}CHO \overset{NaOH}{\longrightarrow} C_{6}H_{5}CH_{2}OH + C_{6}H_{5}COONa \]
- Here, benzaldehyde (C₆H₅CHO) has no alpha-hydrogens, allowing it to undergo the Cannizzaro reaction.

3. **Evaluating the Options**:
- **Option A: CH₃CHO (Acetaldehyde)**:
- This molecule has 3 alpha-hydrogens (attached to the carbon adjacent to the carbonyl), so it cannot undergo the Cannizzaro reaction.
- **Option B: CH₃CH₂CHO (Propionaldehyde)**:
- This molecule has 2 alpha-hydrogens, thus it also cannot undergo the Cannizzaro reaction.
- **Option C: CH₃₃CCHO (Trimethylacetaldehyde)**:
- This molecule has no alpha-hydrogens because the carbon adjacent to the carbonyl is bonded to three methyl groups. Therefore, it can undergo the Cannizzaro reaction.
- **Option D: CH₃CH₂CH₂CHO (Butyraldehyde)**:
- This molecule has 2 alpha-hydrogens, so it cannot undergo the Cannizzaro reaction.

4. **Conclusion**:
- The only aldehyde from the options that can undergo a Cannizzaro reaction is **Option C: CH₃₃CCHO**.

### Final Answer:
The similar reaction can take place with **Option C: CH₃₃CCHO (Trimethylacetaldehyde)**.
