Stability, heat of hydrogenation, alkanes/enes/ynes
« on: April 16, 2012, 06:40:01 PM »
Hello!

I'd like to make sure i'm correct about this.

Something with an unstable bond means it will release a lot of energy when the bond is broken and something more stable is formed.

Conversely, something with a stable bond will release very little energy when the bond is broken and something more stable is formed.

So I want to look at heat of hydrogenations of alkyne vs alkene. But first, I have to preface this question:

Are alkynes more stable than alkenes?

OK i'm satisfied with what I learned. Nevermind about my question (which also turned out to be irrelevant to what I was trying to learn, anyway). Thank you again.
