Domain: Chemistry / ball_stick_model

turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A <glass reagent bottle with a ground-glass stopper> contains a substance. This substance must have the following observable appearance: <colorless, liquid, with a high degree of transparency and fluidity>. The background should be a <laboratory environment: a bench surface with basic equipment outlines, avoiding clutter and text labels>.
output: evaluation_points: 1. The generated container is correct and is indeed a <glass reagent bottle with a ground-glass stopper>.

2. The color and appearance of the target substance (colorless, liquid, transparent, fluid) conforms to the described characteristics.

3. The substance is contained appropriately in the bottle, with a suitable fill level (e.g., not overflowing, not nearly empty).

4. The background is a simple laboratory bench scene.

turn: 2
modality: text
input: Based on the appearance of the substance in the input image, and given that this substance is known to have the following properties: 1) It is a highly flammable, volatile liquid with a characteristic aromatic odor. 2) It is immiscible with water and forms a separate layer. 3) It is a common organic solvent and a fundamental starting material in the synthesis of many other compounds. Which of the following substances is it most likely to be?

Options:
A. Ethanol (C2H5OH)
B. Acetone (C3H6O)
C. Benzene (C6H6)
D. Cyclohexane (C6H12)
E. None of the above
output: answer: C

turn: 3
modality: image
input: Please generate a ball-and-stick model of the molecule for the 'target substance' determined in the first half. Use a white background with no text labels. Adhere to the following atomic color scheme: H-white, C-black, O-red, N-blue, Cl-green, S-yellow, P-orange. For any elements not listed, use neutral gray and be consistent.
output: evaluation_points: 1. Correct atom types and counts (consistent with the real molecular composition of benzene, C6H6, no extra or missing atoms).

2. Correct bonding connections (a planar hexagonal ring of six carbon atoms, each bonded to one hydrogen atom, with alternating single and double bonds or a delocalized ring representation).

3. Correct key spatial configuration (a planar, regular hexagonal ring structure should be discernible).

4. Strict adherence to the atomic color mapping from the prompt (C-black, H-white) and consistency throughout the image.

5. Output is a clear ball-and-stick model: reasonable ball-to-stick proportions, uncrowded structure, pure white background.

turn: 4
modality: image
input: Based on the ball-and-stick model generated in the previous turn, modify the molecular structure once according to the following rule and generate the modified ball-and-stick model: <Replace one of the hydrogen atoms attached to a carbon atom in the ring with a chlorine atom (-Cl). The modification should occur at a single, unambiguous position>. Except for the locally modified part, the rest of the structure should remain consistent with the input structure. Use the atomic color scheme from the previous question. White background, no text labels.
output: evaluation_points: 1. Correct modification action (strictly conforms to '<Replace one hydrogen atom with a chlorine atom>', not a different type like addition or elimination).

2. Correct and unique modification site (hits the specified 'single, unambiguous position' on the ring, not at other positions).

3. Self-consistent atom count and bond connections after modification (no valence errors, dangling bonds, extra bonds, or missing bonds; the C-Cl bond is single).

4. Unmodified structural parts remain consistent (the hexagonal ring skeleton and overall planar topology are preserved, though overall rotation/viewpoint may change).

Unmodified structural parts remain consistent with the structure from turn 3 output (the hexagonal ring skeleton and overall planar topology are preserved, though overall rotation/viewpoint may change).

Strict use of the atomic color mapping from the turn 3 prompt (C-black, H-white, Cl-green). The new chlorine atom follows the scheme.
