Question

Which one of the following is correct statement?

• A. cis-cyclooctene is more stable than it trans form
• B. trans-cyclooctene is more stable than it cis form
• C. both trans-cyclooctene cis-cyclooctene are equally stable
• D. None of the above

Answer 1

The correct option is A cis-cyclooctene is more stable than it trans form

cis-cyclooctene is more stable than it trans form because of the resulting high ring strain in trans-cycloalkenes while cis isomers show considerable less ring strain. Hence cis form is more stable
