Options

A. 16, 16
B. 16, 20
C. 20, 16
D. 18, 18

Answer

To determine the number of carbon atoms in arachidonic acid and palmitic acid, we can follow these steps:

### Step 1: Identify the chemical formula of Arachidonic Acid
Arachidonic acid is known to be an unsaturated fatty acid. Its chemical formula is C20H32O2.

### Step 2: Count the number of carbon atoms in Arachidonic Acid
From the formula C20H32O2, we can see that there are 20 carbon atoms (C).

### Step 3: Identify the chemical formula of Palmitic Acid
Palmitic acid is a saturated fatty acid. Its chemical formula is C16H32O2.

### Step 4: Count the number of carbon atoms in Palmitic Acid
From the formula C16H32O2, we can see that there are 16 carbon atoms (C).

### Conclusion
- Arachidonic Acid has **20 carbon atoms**.
- Palmitic Acid has **16 carbon atoms**.

### Final Answer
Arachidonic Acid: 20 carbons; Palmitic Acid: 16 carbons.
