In geometric isomerism, the trans-isomers have all of the following properties EXCEPT:
Correct answer: B. They have high boiling points
- A. They are non-polar molecules
- B. They have high boiling points
- C. They are symmetrical molecules
- D. They have high melting points
Explanation
Trans isomers are generally more symmetrical, which often leads to them being non-polar. This symmetry allows for better packing in a crystal lattice, resulting in higher melting points. However, their non-polar nature leads to weaker intermolecular forces and thus lower boiling points compared to their polar cis counterparts.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
