Bonds and alkene stability
4× asked, last 2026More alkyl: more hyperconjugation, smaller heat of hydrogenation; then trans > cis. C–C, C=C, C≡C: 154, 134, 120 pm.
Geometrical isomerism
3× asked, last 2026cis polar, boils higher (277 vs 274 K); trans packs better, melts higher. E: higher-priority groups apart.
