Based on the combined effects of hyperconjugation and steric hindrance, select the correct stability — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Tetrasubstituted (12 $\alpha$ -H) > Trisubstituted (9 $\alpha$ -H). Trans is more stable than Cis due to less steric repulsion between methyl groups. Isobutylene (6 $\alpha$ -H) > 1-butene (2 $\alpha$ -H), making C false. Propene (3 $\alpha$ -H) > ethene (0 $\alpha$ -H), making D false.
