[VISUAL]
The structural formulas for two isomers of 1,2-dichloroethene are shown above. Which of the two liquids has the higher equilibrium vapor pressure at 20°C, and why?
A.
The cis-isomer, because it has dipole-dipole interactions, whereas the trans-isomer has only London dispersion forces
B.
The cis-isomer, because it has only London dispersion forces, whereas the trans-isomer also has dipole-dipole interactions
C.
The trans-isomer, because it has dipole-dipole interactions, whereas the cis-isomer has only London dispersion forces
D.✓ Correct
The trans-isomer, because it has only London dispersion forces, whereas the cis-isomer also has dipole-dipole interactions
