Question

The number of geometrical isomers of \( \text{CH}_3 \text{CH} = \text{CH} - \text{CH} - \text{CH}_2 \) is

• A. 2
• B. 4
• C. 6
• D. 8

Hint:

For compounds with double bonds, cis-trans isomerism leads to multiple geometrical isomers.

Answer 1

The Correct Option is B

Step 1: Identify the possible isomers.
The given compound has double bonds that allow for cis-trans isomerism. Since there are 2 double bonds, there are multiple possible isomers, including cis-trans forms.
Step 2: Conclusion.
Thus, the compound has 4 geometrical isomers.
Final Answer: \[ \boxed{4} \]
