This question will cover visualizing emo diagrams and molecular orbitals and how to determine based on visual what sort of bond is happening.
00:11
So if we refer to problem 14 in the book, then we see that question a in part 14, which is two lobes shaded like this.
00:23
It's kind of an inaccurate artist representation here.
00:26
What sort of bond is this? either sigma, sigma star, pi, or pi star.
00:30
So remember it that when we are looking at bonding interactions, that head -to -head interactions, these are going to be sigma bonds and sort of parallel adjacent bonds are going to be pi bonds.
00:41
And we see that in this visual, we're talking about the latter.
00:44
These aren't head -to -head.
00:45
These are adjacent to each other.
00:47
And we actually see that each of these orbitals, their lobes are out of phase with each other.
00:52
So this sort of if these two atoms were next to each other, they could not form a pie bonding interaction.
00:57
So these two orbitals together would be an example of a pi star, that's a pi antibody, anti -bonding orbital.
01:07
Now, the next example that we're given, give an example that looks like this, this, a bonding between an s -orbital and some sort of sp -hybridized orbital.
01:23
What sort of an action would this be? well, we see that these are head -to -head...
