Look here! KZread 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: kzread.info/dash/bejne/e2afmJODfc6dYbA.html

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 !

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!

If you understand how the antibonding thing works for H2 please lemme know. I get it if there are 2 electrons from each like 1s2... sure one from each go to the sigma and "sigma star" whatever that is. But with h2 there are ONLY 2 ELECTRONS.

Hi, what does it mean for 2 atomic orbitals to be added head to head or tail to tail?

Why do 2 atomic orbitals with opposite signs added head to head or tail to tail form an antibonding molecular orbital?
