Why do Trans geometrical isomers generally exhibit significantly higher melting points than their co — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Melting point heavily depends on solid-state packing efficiency. Trans isomers feature substituents symmetrically opposed, giving them a linear profile. This allows them to pack extremely efficiently into a robust crystalline lattice, resulting in a higher melting point than the bulky, "U-shaped" cis isomers.
