1. True. trans -Cyclohexene is too strained <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/72f0602819b127c76f64a7ed4b1f36f4-.png" /> 2. False. Eight-membered or larger rings can have a trans-substituted (C=C) in the rings. So eight-membered or larger rings are more stable in trans forms 3. False 4. True

Q. Which statements is/are correct about cyclohexene and cyclodecene?

$Z$ or cis-cyclohexene is more stable than $E$ or trans-isomer

$Z$ or cis-cyclodecene is more stable than $E$ or trans-isomer

$Z$ or cis-cyclohexene is less stable than $E$ or trans-isomer

$Z$ or cis-cyclodecene is less stable than $E$ or trans-isomer

1. True. trans -Cyclohexene is too strained

2. False. Eight-membered or larger rings can have a trans-substituted $(C = C)$ in the rings. So eight-membered or larger rings are more stable in trans forms
3. False
4. True
