Question

The number of stereoisomers possible for a compound of the molecular formula \( \text{CH}_3 \text{CH} = \text{CH} - \text{CH} - \text{CH}_2 \) is:

• A. 2
• B. 4
• C. 6
• D. 8

Hint:

Compounds with multiple double bonds can exhibit cis-trans isomerism at each double bond, increasing the number of stereoisomers.

Answer 1

The Correct Option is B

Step 1: Analyze the compound.
The given compound has two double bonds and can exhibit cis-trans isomerism at both the positions, leading to a total of 4 stereoisomers.
Step 2: Conclusion.
Thus, the compound has 4 stereoisomers.
Final Answer: \[ \boxed{4} \]
