State the boiling point of cis-3-hexene and trans-3-hexene?

Answer 1

boiling point in cis-3-hexene is higher than in trans-3-hexene

Why?

1- in cis the compound is more polar ( dipole-dipole interaction)

2- and also it is effected by london forces

So, cis needs more energy to break up this compound , that's mean high boiling point is required here

let's see the Trans-3-hexene

1-there are slightly positive and negative charge in opposite direction so they cancel each other ( dipole-dipole interaction) is not effected here

2- there are just london forces so less energy is require means lower boiling point

:)

Answer 2

The boiling point of cis-3-hexene is approximately 120°C, while the boiling point of trans-3-hexene is slightly lower at around 117°C.
