To determine which functional groups are represented in the molecular structure, we would need to analyze the specific atoms and bonds present in the structure. Since the molecular structure is not provided, I cannot specify which options are correct.
However, I can explain the functional groups mentioned:
- Methyl group (-CH₃): A carbon bonded to three hydrogens.
- Amino group (-NH₂): A nitrogen bonded to two hydrogens.
- Carboxyl group (-COOH): A carbonyl group (-C=O) and a hydroxyl group (-OH) bonded to the same carbon.
- Sulfhydryl group (-SH): A sulfur atom bonded to a hydrogen.
- Hydroxyl group (-OH): An oxygen bonded to a hydrogen.
Depending on the structure you have, you can identify which of these groups are present and choose the correct option. If you can provide more details or the actual structure, I can assist you better in determining the correct functional groups.
