The following apply to the oxygen molecule, O2:

(a)   bond order 2, 2 unpaired electrons

         (b)   bond order 2, no unpaired electrons

         (c)   bond order 1, 2 unpaired electrons

         (d)   bond order 1, no unpaired electrons

         (e)   bond order 1½, no unpaired electrons

_________________________________________

The bond order in C2- would be:

         (a)   1     (b) 1.5 (c) 2 (d) 2.5 (e) 3

Please show the steps for the above two questions, I'm little confused about the bond order and the pair electron in these two questions.

I do rate the answer, so please answer it best you can.
