I'm completely lost after seeing this video https://youtu.be/AAmqeHCFq_8 (starts at 6:50) and reading some more about this topic.
What I understand so far is that energy is NOT stored in chemical bonds (even though most textbooks say it is). But where is the energy stored then and in what form? And how does it work? I'm a biochemistry undergraduate trying to understand this, but I can't get my head around it.
Well that was retarded. Im not entirely sure what he was trying to get, but I think its that the "energy in a chemical bond" is actually potential energy, like when you raise a ball some night off the ground it would be improper to say that the ball has energy or that the ball stores energy.
I've got to say if that is what he's saying then its one of the more autistic gripes I've seen, worse still since he didn't express what he was trying to say that well.
Ss he said. Energy was needed to produce a more complicated structure. Every part of the molceule trys to get to a more stable, ledd energy dense state.
Same like cole or oil. Energy has been transfered into it by pressure over long periods of time. If you burn it this energy is released since the molecul gets split into lower molecules and the energy that was used to bond it together is set free.
Non native speaker here but i'll try to help you
Your picture is from spectroscopy, that a good way to study energy level of molecules ( electron, vibration and rotation.) but you don't need this
wave/particle duality : wave is from quantum chemistry, i can't explain that but it's from Schrödinger equation.. An electron isn't a small ball, and molecules aren't a battery, there is no storage energy (go back energy level)
When i write this i don't think it's will help you but you really don't need to try to undestand why and where is the energy, chemical structure and reactivity cn help you, molecular orbital etc too
But the whole points is that it is the formation of chemical bonds that releae energy, not directly the breaking down of chemical bonds.
So how does a chemical bond have energy when it costs energy to break it down
