    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

    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.
    but I'm not sure.

    Please help me
    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.
