Chemical_Kitten Stupid pi and sigma bonds!!! Can anyone explain hybridisation to me??? Wellzy?? crying Hybridisation is nast, nasty nasty nasty. And yet in some instances surprisingly simple. biggrin
TO understand the difference between pi and sigma bonds, you do understand tha basic principal of hybridisation, yes? In this case, I'll refer to sp hybridisations. You have your basic nodal shape. Now, a sigma bond is when a node bonds to another node along the internuclear axis. So, if you draw a line through the centre, where all the nuclei should be, you will also run through the over-laps of the nodes. This is much easier if you visualise it. sweatdrop
A pi bond is of course, the opposite. The nodes overlap in a side-on manner, and aren't in like the with internuclear axis.
Did that help? That so didn't help did it?

WellzY Chemical_Kitten Thanks Wellzy, I love your pictures!! heart I'm looking at it, and I just don't get all the node stuff. The MO stuff just confuses me. I mean, you've got bonding pairs and non-bonding pairs in the sigma bond stuff and I just don't get it. Why would you have non-bonding pairs in a bond? Don't "non-bonding" mean that they don't bond? Well, you have been tought about the shape of the s subshells and the p subshells yes? The VSEPR Theory bases bonding observations on the shape of such subshells, and hybrid subshells help to explain how certain elements bond in molecules that can't be explain by the... other theory. xd I think I need pictures again for this. Nope, I've lost myself. Do you need help now? I'm trying to do biology study at the moment, but I could help you on MSN later. Thanks for all your help, I'm so confused by it all. I can wait if you want to study for biol, I can't expect you to drop everything for my problems. Thanks for all your help heart .
