I had accidentally posted this last night to ualrchem1402 instead of public but my question was:The central element is the least electronegative?
-
The "octet rule" says that in many compounds the most stable (correct) electron configuration is when there are 8 electrons (four filled orbitals). This is a consequence of the fact that many compounds involve the S and P block electrons, which contribute 4 orbitals and can thus contain 8 electrons.
I remember that there are exceptions to breaking the octet rule. Isn't it that elements in period 3 or below are capable of breaking it if need be?
