Look here! KZbin is deleting all annotations, which I have used in the past to make corrections, so I want to make sure everyone knows that at 0:16, 1:58, 2:12, and 2:40, I say "molecular orbitals" but I meant "hybrid atomic orbitals". Also, for the molecular orbital diagram for N2, the pi 2p bonding orbitals should be below the sigma 2p bonding orbital due to s-p mixing. These are major errors so please make the correction in your head, sorry! I've been much more careful about triple checking my work since these early videos, I promise. UPDATE! This new video about MO theory is much clearer, please watch the new one immediately after this one to get some clarity: kzbin.info/www/bejne/f2POZ2SAgtBqZ68

Thanks for great explanation and care for delivering accurate information . But I have an enquiry about molecular orbitals ... Molecular orbital theory assumes that number of atomic orbitals = number of molecular orbitals , for example in case of formation of H2 molecule there is two atomic orbitals that formed one molecular orbital ( the bonding orbital) , but I can not understand how the other(anti bonding ) orbital is formed .. can you explain it please !
@ProfessorDaveExplains6 жыл бұрын
Check out my classical physics tutorials on wave mechanics, the bonding orbital is the result of constructive interference and the antibonding is the result of destructive interference!

Hello! Your videos really help me now during my university courses! Thank you! But I have a number of questions: 1. Are all pi bounds degenerate? So if you have a molecule of N_2 or F_2 och Cl_2, how would their diagrams differ? 2. Is it correct that if you want to answer the question e.g " Explain the structure of a water molecule with Valence bond Theory", that one should start with determind the "atomic valence orbitals" for oxygen and hydrogen, sen try to figure out optimal structure (with oxidation numbers or formal charge) and then go onto figuring out the molecular orbitals? 3. Bonding order is the same as the number of bounds between molcules on the form "X_2" (Like N_2), given that they can exist? Thank you!
@ProfessorDaveExplains8 жыл бұрын
1) not sure i understand the question, the molecular orbital diagrams differ because the atoms making up the molecule have different identities therefore differing numbers of electrons to place in the diagram. 2) if using valence bond theory, we are using hybrid orbitals, so for water that means an sp3 hybridized water molecule, with sp3 orbitals overlapping with hydrogens 1s orbital to make covalent bonds. 3) yes, bond order tells us the number of bonds between two atoms.

in reality, the orbitals on CH4 are NOT degenerate, and one of the reasons is because hybridisation is strictly a mathematical concept, if you actually perfect photoionization spectroscopy on CH4, you will find 3 bonding orbitals higher in energy than the lowest energy bonding orbital. hybridisation is just an outdated model sadly, it works for carbon as far as predicting shapes (in organic compounds) but try using this model for anything else (and i really mean ANYTHING else) and it falls apart.
