![**Question 1: Diene Analysis**
**Text:**
For the following dienes, identify whether the molecules have any cis or trans stereochemistry and identify the conformation as either s-cis or s-trans, where appropriate. Please also note whether the compound would be reactive in a Diels-Alder reaction.
**Diagram Description:**
The diagram shows three chemical structures of dienes:
1. **First Diene:**
- Structure:
```
H3C
│
H3C=C
│
CH3
```
- The molecule has a bromine (Br) attached and two methyl (CH3) groups attached to the carbons of the double bonds.
2. **Second Diene:**
- Structure:
```
CH3
│
H2C=C
│
CH3
```
- This molecule shows a simple diene with two methyl groups attached to the carbons of the double bonds, but no additional details visible in this diagram.
3. **Third Diene:**
- Structure:
```
H3C H3C
│ │
H3C=C C=CH
│ │
Br Br
```
- This molecule features two bromine (Br) atoms along with methyl groups (CH3) attached to the carbons involved in the double bonds.
**Points to Consider:**
1. Identify **cis** or **trans** stereochemistry for each diene.
2. Determine if the diene exists in an **s-cis** or **s-trans** conformation.
3. Assess whether the diene is likely to participate in a **Diels-Alder reaction** based on its conformation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F86fb4fea-474a-4bf3-af54-6f23562d8d8b%2Fce8f5ac3-acc7-4556-917a-6b63bedbc9ff%2F2vvfzrx_processed.jpeg&w=3840&q=75)
