Cis Trans Stability Boiling point logic

[onedirection]

I was wondering what the logic was behind the boiling point differences with cis and trans versions of the same thing

So from what I understand, trans products are more stable because there are fewer steric hinderances there

What I figured was because they are more stable, they are less likely to react

So then if they are less likely to react, wouldn't that mean that they have higher boiling points than the cis products?

I don't understand why exactly cis has a higher boiling point

Why is it that the more reactive it is the higher the boiling point while the more stable one has a lower boiling point?

Typically, the cis isomer has a slight polarity whereas the polarity in the trans isomer cancel each other out, making them nonpolar. Since the trans isomer is nonpolar, their IMFs are weaker than the polar cis isomers, making them easier to separate from each other, and therefore vaporize more readily.

Stacking plays a role in melting points, so the same logic can't be used for that. Trans isomers have higher melting points than cis isomers due to their ability to stack, which increases the intermolecular interactions between each other.

Vaporization (boiling) is not a chemical reaction, so the thermodynamic stability you're referring to between the isomers is unrelated; they don't "react" to vaporize.
