Thread: Bonding

I just had an MC exercise but am not very sure on the answers for the following questions

Can someone help me plz? There are 2 short questions in total.


Which of the following contain localised (but not delocalised) π(pi)-bonding?

BeF2
CO3(2-)
CO2
H2CO
H2O
NO3(1-)
SF4
O3


Which of the following contain delocalised π(pi)-bonding?

BeF2
CO3(2-)
CO2
H2CO
H2O
NO3(1-)
SF4
O3




Please help me

I'm not sure either, is there one corect answer or are there more then one because for question two I found they were all correct except for O3.

If you have a double bond it would have π(pi)-bonding.
If you have more then 2 pi orbitals at neighbour atoms it is delocalized.
