Explanation:

Since the problem is not clearly stated (e.g., identifying the compounds, their functional groups, or another task), I'll assume a common task like naming the compounds or identifying functional groups. Let's analyze each structure:

First Structure (Left):

• Formula: \( \text{CH}_3\text{COCH}_3 \) (Acetone, Propanone)
• Functional Group: Ketone (\( \text{C}=\text{O} \) bonded to two alkyl groups)

Second Structure (Middle):

• Formula: \( \text{CH}_3\text{CH}_2\text{CH}_2\text{CHO} \) (Butanal)
• Functional Group: Aldehyde (\( \text{C}=\text{O} \) bonded to a hydrogen and an alkyl group)

Third Structure (Right):

• Formula: \( \text{C}_2\text{H}_5\text{OH} \) (Ethanol)
• Functional Group: Alcohol (\( -\text{OH} \) group bonded to a carbon)

If the task was to identify the functional groups:

• Left: Ketone
• Middle: Aldehyde
• Right: Alcohol

If you meant another task (like naming, molecular formula calculation), please clarify. For molecular formula calculation (e.g., third structure: \( \text{C}_2\text{H}_6\text{O} \)):

Step 1: Count atoms

• Carbon (\( \text{C} \)): 2 (from two \( \text{C} \) atoms)
• Hydrogen (\( \text{H} \)): 6 (each \( \text{C} \) has 3, but one \( \text{C} \) has \( -\text{OH} \), so \( 3 + 3 = 6 \))
• Oxygen (\( \text{O} \)): 1 (from \( -\text{OH} \))

Step 2: Write formula

\( \text{C}_2\text{H}_6\text{O} \)

Since the problem is unclear, please provide more details (e.g., "Identify the functional group of the right structure" or "Name the left compound") to get a precise answer.
