Question
  1. Draw cis and trans-structures for Hex-2-ene. Which isomer will have higher boiling point and why?
  2.  

✓

Answer

  1.  

cis-Hex-2-ene has higher dipole moment and therefore, it has higher boiling point.

  1.  

 is not aromatic, Due to the presence of sp3

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.
