Question

what is the missing product/reactant in each reaction?

## Part B ### Organic Chemistry Reaction: Hydrogenation #### Reaction Scheme: ``` ? ———— H₂ Pt catalyst ————————> Cyclohexane ``` ### Explanation: This image illustrates a chemical reaction where an unknown reactant (denoted as "?") undergoes hydrogenation in the presence of a platinum (Pt) catalyst and hydrogen gas (H₂) to produce cyclohexane. #### Detailed Diagram Description: - **Reactant**: Represented by a question mark (?), indicating the substance before the reaction is unknown. - **Reagents**: Hydrogen gas (H₂) and a platinum catalyst (Pt catalyst) are provided above and below the reaction arrow. - **Product**: The product of this reaction is cyclohexane, a six-membered carbon ring, typically represented as a hexagon. #### Instructions: **Draw the molecule on the canvas by choosing buttons from the toolbars.** This instruction suggests that users are expected to use a digital drawing tool to depict the appropriate structures for the chemical components described in the reaction. ### Educational Insight: The hydrogenation reaction is common in organic chemistry, often applied to convert alkenes or alkynes into alkanes. Here, the presence of a platinum catalyst and hydrogen gas usually implies the hydrogenation of an unsaturated compound to form a saturated cyclic hydrocarbon, cyclohexane. The task may involve identifying the starting material that, when hydrogenated, produces cyclohexane.

### Chemical Reaction Representation #### Reaction A: **Reactant:** - The structure is a five-membered cyclic compound (a cyclopentene) with one double bond extending outwards from the ring structure. **Reaction Condition:** - The reactant undergoes hydrogenation with Hydrogen gas (\( \text{H}_2 \)) in the presence of a Platinum (Pt) catalyst. **Goal:** - To determine the resultant product of this reaction. **Instructions:** - Draw the molecule on the given canvas by using the appropriate tools provided in the drawing interface. #### Tools and Interface: - The interface below the instruction includes tools for drawing chemical structures with buttons for various functionalities: - Undo - Redo - Zoom in/out - Select - Erase - Add hydrogen atoms - Add other elements - Add bonds - Modify structure properties This diagram is part of a larger exercise in understanding organic reaction mechanisms, specifically focusing on the hydrogenation process.
