What is the hybridization of oxygen or nitrogen in each of the following?
Okay. So here we have to calculate the hybridization but not only one nitrogen but two, let's take it one nitrogen at a time, where I start with this one and we're going to move on to this one. So, for the first one, we always need to ask ourselves for hybridization how many things is it attached to, right? so it's CH4, Carbon with four things, four hydrogens, right? this is going to have what kind of hybridization? Well, connected to 1, 2, 3, 4 things, so we're going to expect that carbon to be sp3 hybridize. So, for this nitrogen how many things is it attached you? Well, this nitrogen, this carbon, and is that it? no, because we have this lone pair, so it's going to be sp2 hybridized. So, go ahead and try to do the other nitrogen using the same technique. Remember, that lone pair is an account as well, so hopefully you that these guy that is connected to another nitrogen, this lone pair remember we said it's going to count as well notice that we have two hydrogen groups, so we're going to actually count both of them, so what that means is that you have a nitrogen that's double bonded, it's connected to two hydrogens and it has a lone pair. So we're going to say this is 1, 2, this hydrogen would be 3 and this one would be 4, so it actually has an SP3 hybridization, okay? So that first nitrogen we said was SP2 and the second one we said was actually SP3, okay? So, let me know if you have any questions.
