Domain: Chemistry / ball_stick_model

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

2. The color and physical form (powder/crystal/lump/solution, etc.) of the target substance conform to '<colorless, clear, transparent liquid>'.

3. The substance is appropriately contained in the bottle, with a suitable fill level.

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 has a characteristic, pleasant odor. 2. It is highly flammable and burns with a pale blue, nearly invisible flame. 3. It is miscible with water in all proportions.>, please select the substance it most likely is from the following options:

Options:
A. Acetone (CH3COCH3)
B. Ethylene Glycol (HOCH2CH2OH)
C. Glycerol (C3H8O3)
D. Acetic Acid (CH3COOH)
E. None of the above
output: answer: E

turn: 3
modality: image
input: Please generate the ball-and-stick model of the target substance determined in the first half. Use a white background with no text labels or annotations. Please 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 ethanol, C2H6O, with no extra or missing atoms).

2. Correct bonding connectivity (key bond connections and branch connections are accurate, overall structure is self-consistent).

3. Correct key spatial configuration (consistent with the common/stable configuration of ethanol; the tetrahedral geometry around carbons and the bent shape of the -OH group should be discernible).

4. Atomic coloring strictly follows the color mapping table in the prompt and is consistent throughout the image (the same element should not appear in multiple colors).

5. Output is a clear ball-and-stick model: reasonable sphere and 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 the hydroxyl group (-OH) on the terminal carbon with a chlorine atom (-Cl).> 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. The modification action is correct (strictly conforms to '<Replace the hydroxyl group (-OH) on the terminal carbon with a chlorine atom (-Cl).>', no incorrect modification type: substitution/addition/elimination, etc.).

2. The modification site is unique and correct (hits the 'terminal carbon' specified in the prompt, no substitution at other positions).

3. The atom count and bond connectivity of the modified structure are self-consistent (no valence errors, dangling bonds, extra bonds, or missing bonds).

4. The unmodified structural parts remain consistent (skeletal topology and main configuration are consistent with the input; overall rotation/viewpoint changes are allowed but connection relationships must not change).

The unmodified structural parts remain consistent (skeletal topology and main configuration are consistent with the ball-and-stick model generated in turn 3; overall rotation/viewpoint changes are allowed but connection relationships must not change).

Atomic coloring strictly follows the atomic color scheme specified in turn 3's prompt (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); newly added atoms also adhere to this scheme.
