Answer 1

Answer:

cis isomers have higher boiling points as they are more polar and less symmetrical...!

Answer 2

Answer: Cis compound will have more boiling point than trans one.

Explanation:

The boiling point is decided by two parameters : Molecular mass and polarity. In cis and trans compounds, most of them have same molecular mass but polarity of cis compound is more than trans compound. Because in trans, the same bonds are exactly opposite each other thus making dipole moment equals to zero but cis gives resultant dipole moment. Thus boiling point of cis is more than trans.

For deciding melting point, the first and foremost parameter is symmetrical order and crystallinity. In trans compound, symmetry is more whereas in cis, symmetry is less. Thus trans has higher melting point than cis.
