Question

For each type of bond below, determine the direction of the expected dipole moment. 

(a) C–O 

Video Transcript

Hey guys. So, in this problem we need figure out the direction of the dipole moment in each type of bond that we have, okay? that I'm going to go ahead and draw. Now, in a second but guys a really quick way to determine the direction of the dipole moment is to just figure out that, just remember that the electronegativity is what dictates it, okay? So the dipole moment will flow, it will point in the direction the more electronegative atom, okay? And guys we have a little trend that we can remember, right? That's definitely going to help us out here in certain situations, okay? Especially when we're dealing with these, okay? So guys in the entire periodic table what happens is that as we move to the right, okay? As we move to the right and up we actually increase the electronegativity, so guys chlorine is the most electronegative atom there is, okay? So guys actually something that's all the way to the left it's not going to be very electronegative, so the diole is most likely not going to point toward it, okay? Same thing for something that's at the very bottom, okay? But the more to the right in to the bottom it is, sorry, more the right and to the top it is the more electronegative it is, so guys, what about a bond between carbon and oxygen? Well, if we take a look oxygen is more to the right than our carbon, right? there's more electronegative, so the dipole is going to point toward the oxygen, okay? we're about carbon and magnesium? Well guys, magnesium is actually very, very far to the left, okay? And it's I think if I remember correctly its electronegativity value is somewhere around 1, maybe 1.3, something like that, and guys that's definitely going to have a dipole moment pointing this way since our carbon has a 2.5 electronegativity value, okay? It's all the way over here, okay? So now what about these next ones? what about carbon to nitrogen, well, it's more to the right well it's more like negative, our nitrogen, so we expect to find a dipole going this way, right? How about carbon lithium, carbon chlorine, carbon hydrogen, OH and NH, okay? let's go through this really quickly, carbon and lithium same situation as magnesium, right? It's the lithium is very far to the left. So, our electronegativity, our more electronegative atom is the carbon, how about carbon and chlorine? chlorine is more electronegative. So, dipole is going to pole this way, carbon and hydrogen? Okay, well this one is very interesting because it is classified as a covalent bond even though it just barely makes the polar covalent threshold, right? It's 2.5 for the carbon 2.1. So, it's in 0.4, so it's very, just very slightly polar covalent, so if you were to ask for a dipole it will be pointing toward the carbon since the carbon is more or electronegative, how about OH? oxygen is more electronegative, it's one of the most electronegative atoms there is, right? Okay, there are, and over here nitrogen versus hydrogen, nitrogen is more electronegative than our hydrogen, okay? So we're going to have a dipole pointing this way. Alright guys I hope that helps, let's move on to our next question.
