Stereochemistry and Properties of 2-Butene

Hard Organic Chemistry Stereochemistry

A researcher is studying the effects of stereochemistry on biological activity and encounters the compound 2-butene. This compound has two stereoisomers: cis-2-butene and trans-2-butene. She notes that the cis-isomer has higher boiling points compared to the trans-isomer due to the differences in molecular interactions. Understanding these concepts is crucial for the development of new drugs.

Which of the following statements regarding the stereochemistry of these two isomers is correct?

Cis-2-butene has a lower vapor pressure than trans-2-butene due to stronger intermolecular forces.

Trans-2-butene is more polar than cis-2-butene.

Both isomers exhibit equal constitutional isomerism.

Cis-2-butene contains two different substituents, making it a chiral molecule.
