Question

Following compounds are respectively ... geometrical isomers

• A. \( \text{cis} \), \( \text{cis} \), \( \text{trans} \)
• B. \( \text{cis} \), \( \text{trans} \), \( \text{trans} \)
• C. \( \text{trans} \), \( \text{trans} \), \( \text{cis} \)
• D. \( \text{cis} \), \( \text{cis} \), \( \text{cis} \)

Hint:

Geometrical isomerism is observed when two groups or atoms can occupy different positions around a double bond or a ring structure.

Answer 1

The Correct Option is A

Step 1: Identifying isomers.
The compounds are described as geometrical isomers, and the given options are evaluated based on cis-trans isomerism. Option (1) provides the correct sequence of cis and trans forms.

Step 2: Conclusion.
The correct answer is \( \text{cis} \), \( \text{cis} \), \( \text{trans} \), corresponding to option (1).
