Question

The image displays a chemical structure. To identify the compound, we need to analyze its features:

1. Ring Structure: The molecule is cyclic, forming a five-membered ring.
2. Functional Groups: There are two carbonyl groups (C=O) present in the ring.
3. Position of Functional Groups: The two carbonyl groups are located on adjacent carbon atoms within the ring.
4. Saturation: The remaining carbon atoms in the ring are saturated (implied by the skeletal structure, meaning they are CH₂ groups).

Based on these observations:

• The parent ring is a cyclopentane.
• The presence of two ketone groups makes it a diketone.
• Since the ketone groups are on adjacent carbons, they are at positions 1 and 2.

Therefore, the compound shown in the figure is Cyclopentane-1,2-dione.

The structure can be represented as:

      O
     //
    C1----C2=O
   /        \
  CH2        CH2
   \        /
    CH2

The SMILES notation for this compound is: O=C1C(=O)CCC1

Answer 1

Cyclopentane-1,2-dione

Answer 2

The image depicts a 5-membered cyclic structure containing two adjacent carbonyl (C=O) groups. This arrangement corresponds to a 1,2-diketone within a cyclopentane ring, hence named Cyclopentane-1,2-dione.
