Chemical bonding - spin of bonded electrons

  1. Mar 31, 2006 #1
    Can anybody here please explain to me about the spin of an electron in the covalent bond? My textbook just says that it follows the Hund’s rule. Moreover I am confused with one more statement in the text – it says that in a covalent bond, in the bonding molecular orbital the electrons tend to be nearer to the more electronegative atom is acceptable as well as trivial, but not so is the next statement that on the other hand in anti-bonding orbital the electrons tends to be more nearer to the less electronegative atom.
    I just want a detailed explanation on the following things. I had thought till now that I know exactly what anti-bonding is but the above statement has fully confused me. Please explain.

    2 electrons in the same level in a covalent bond spin opposite of eachother...

    At least i think that was what you were asking

    Their perspective deals with the interaction of atomic orbitals to form molecular orbitals, if you want the fundamental details you're gonna have to delve into some group symmetry topics. An example is carbon monoxide, the HOMO is associated with the carbon, and thus any organometallic bonds is through the carbon; oxygen contributes most of its atomic orbital character to the lower energy molecular orbitals, and has less to contribute to the higher energy orbitals, and thus the higher energy orbitals are largely associated with the carbon end of the molecule, as the HOMO. A standard inorganic chemistry text should give you some good exposure on the topic, a nice preview of the things to come, if you plan on taking advanced chemistry courses.
