hi please help. thankyouuu :]
i am studying for my apchem exam in may.and got stuckup on a question. it's just a little exercise.so the answers aren't there.but ok here it is;
give the resonance structures of PO4 (3) and there's supposed to be four
none?
i started drawing it so..
PO4 (3) = 5 + (6*4) +3 = 32/2 = 16 pairs of electrons so...
O

O  P  O

O
so there's the single bonds (8 electrons: octet rule) for P and then 6 electrons around each O to complete O's octet rule.
and my problem is...where's the dang resonance structure? because everyone gets their electrons.and is happy. unless of course P has an expanded octet and gets more than 8?
i don't know. please help me. thankuuuu
'ppreciate it alottttt.
