- 2,2-dimethyl propanal
- Propanal
- Benzaldehyde
- 2,2-dimethyl propanal and Benzaldehyde
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Quick test
Look for the carbon next to the CHO group and check whether it carries a hydrogen.
Step 2: Apply
Propanal: $\text{CH}_2$ next to CHO has hydrogens. The other two have none.
Step 3: Eliminate
This removes options A, C and D.
Final Answer:
The correct choice is propanal. \[ \boxed{\text{(B) }\text{Propanal}} \]
