After finding hypervalent molecules in my textbook (PF5, SF6) I went on wikipedia to search. THe explanation was a three centre four electron bond. I searched three centre four electrons on google and there came out four centre two electron bonds, three centre two electron bonds etc.
But there are no explanations I can understand! There are mad drawings of antibonding and bonding orbitals and all that BS@#$ and now I am left with only YOU to help me.
Please reply. Extra mole snack for the first person to reply CORRECTLY.
