cis and trans isomers of alkenes: the C=C double bond stops rotation.
Open the interactive simulation →How to use this simulation
- Choose “cis / trans” and a compound.
- Switch between the cis and trans isomer.
- Drag “Try to twist the C=C bond” and read the energy cost.
- Compare boiling points and dipole moments.
What to notice
- Twisting the C=C breaks the π bond — far too costly at room temperature.
- The trans isomer often has no overall dipole.
