Question
- Draw cis and trans-structures for Hex-2-ene. Which isomer will have higher boiling point and why?
✓
Answer
cis-Hex-2-ene has higher dipole moment and therefore, it has higher boiling point.
is not aromatic, Due to the presence of $\mathrm{sp}^3$
carbon (carbon 3), the system is not planar, Futher, it contains only four n electsons. Hence, it is not aromatic because it does not contain planar delocalised cloud with $\text{(4n} + 2)\pi$ electrons.
