Video transcript

Hello. In this problem we are asked to classify each of these molecular orbital representations as constructed from two s atomic orbital zor two P atomic orbital. Looking at the first one we see we have this lobe shape which is indicative of P orbital's we have side by side overlap and we have a nodal plane that runs through the nuclei and is perpendicular to the electron density within the lobes. So one is formed from two P atomic orbital. We look at the second one began have this lobe shape like the p atomic orbital's. We have two nodal planes. One runs through the nuclei and the other is perpendicular to this. This is again indicative of P orbital. So we have to pee common core panels And the 3rd 1 we have more or less a spherical shape. Then we have electron density surrounding both nuclei. We don't have any nodes or nodal planes. This is indicative of then S. For blows Which are spherical in shape. So this has been constructed from two s atomic overhauls. Please then correspond to answer D. Thanks for watching. Hope This helped
