Question
![**Question 26**
**Which compound is an aldehyde?**
Four chemical structures (A, B, C, D) are presented.
- **A**: A structure with a carbon chain that includes a carbon double-bonded to oxygen, with hydrogen atoms bonded to the carbons.
- **B**: A structure with a central carbon double-bonded to oxygen and single-bonded to three hydrogen atoms.
- **C**: A structure with a carbonyl group (C=O) bonded to a CH2 group and a CH3 group.
- **D**: A structure with a carbonyl group (C=O) bonded to a CH3 group and a CCl3 group.
The options provided for answering the question are:
- C
- D
- B
- A
[Graph Explanation]
The graphs provided in this question are molecular structures:
- **Option A** shows a linear arrangement of carbon atoms with a carbonyl group (C=O) and several hydrogen (H) atoms.
- **Option B** presents a similar structural arrangement, focusing on a central carbon atoms double-bonded to oxygen.
- **Option C** is characterized by a carbonyl group flanked by a methylene (CH2) group and a methyl (CH3) group.
- **Option D** displays a carbonyl group bonded to a methyl group and a trichloromethyl (CCl3) group.
**Answer:**
To identify the aldehyde, note that aldehydes have a carbonyl group (C=O) bonded to at least one hydrogen atom.
In this case, correct option indicating an aldehyde structure is:
- **B**, where a carbonyl group is bonded to a carbon with two hydrogen atoms (H).
Select option B.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F950ccb0b-88f0-424e-a789-46ed3bd2a086%2Fa3439adf-074d-489d-a543-38111a261e37%2F3fj75hp_processed.jpeg&w=3840&q=75)
