Question
**Prompt:**

Name and draw the structure of all the alkenes which could undergo catalytic hydrogenation at 900°C to form methylcyclopentane. Circle the alkene with the highest stability and X the alkene with the highest heat of hydrogenation. Give reasons for your choice.

**Explanation for Educational Website:**

This prompt requires students to identify and illustrate all possible alkenes that can be hydrogenated to yield methylcyclopentane. The task involves three main components:

1. **Identification and Drawing:**
   - Students need to recognize which structural alkenes are capable of transforming into methylcyclopentane through catalytic hydrogenation.
   - Detailed structural drawings of these alkenes should be provided.

2. **Stability and Heat of Hydrogenation:**
   - The alkene with the highest stability should be circled. Generally, more substituted alkenes tend to be more stable due to hyperconjugation and the inductive effect.
   - The alkene with the highest heat of hydrogenation should be marked with an "X". Alkenes that are less stable have a higher heat of hydrogenation.

3. **Reasoning:**
   - Students should include explanations for their choices, referencing concepts such as alkene stability (based on substitution patterns) and exothermic hydrogenation reactions (linked to stability). 

This exercise helps students comprehend key aspects of alkene chemistry, including structural analysis, stability factors, and the thermodynamics of hydrogenation reactions.
