Verified step by step guidance

1. Examine the chemical structure provided in the image. Identify the different functional groups present by looking for characteristic atoms or groupings of atoms.
2. Look for a carbonyl group (C=O) bonded to two carbon atoms, which indicates the presence of a ketone. In the structure, identify if such a group exists.
3. Identify any hydroxyl groups (OH) attached to a carbon atom, which would indicate the presence of an alcohol. Check the structure for these groups.
4. Search for an ester group, which is characterized by a carbonyl group (C=O) adjacent to an ether linkage (C-O-C). Locate this group in the structure.
5. Identify any nitrile groups, which are characterized by a carbon triple-bonded to a nitrogen (C≡N). Check if this group is present in the structure.
