Question

At high temperatures, sulfur vapor is predominantly in the 
form of S21g2 molecules. 
(a) Assuming that the molecular orbitals for third-row diatomic 
molecules are analogous to those for second-row molecules, 
construct an MO diagram for the valence orbitals of S21g2.

Accepted Answer

Well everyone's in this video we're trying to do is provide the M. O diagram for the valence orbital of P. Two. So let's go ahead and draw this M. O diagram. So phosphorus is in Group 58. So we'll get five valence electrons per atom here we have two of those, so five times two is equal to 10. So for the M. O diagram orbital's from going from bottom to top, we have our sigma three s that right above that, we'll have our sigma star for three S. Then we'll have our p orbital so we'll have 12. This is going to be our pi three P. Right above that. We have our sigma three P. Then we'll have our anti bonding of those two. So then we'll have to here that's going to be our pi star three P. And lastly our sigma star three P. Again we're doing this for P two. Alright, so again we just said that each phosphorus atom gives us five valence electrons will have two of those atoms and that will go to 10 total valence electrons. Let's go ahead and fill that in. So we'll have and 10. So this right here is going to be our M. O diagram for the valence orbital's of our P two molecule and this right here is my final answer. Thank you all so much for watching
