When comparing the macroscopic physical properties of standard Cis and Trans geometrical isomers, wh — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

In a trans isomer, identical groups are strictly opposite ($180^\circ$), and their individual bond dipole vectors often cancel each other out (making $\mu = 0$). In the cis isomer, the vectors add together constructively, yielding a highly polar molecule with a net resultant dipole moment ($\mu \neq 0$).
