Expert Answer:

According to VBT
O - 1s2 2s2 2p4
2px is filled with 2 electrons.
Singly 2pz wil overlap with singly occupied 2pz to form a sigma bond.
Singly 2py wil overlap with singly occupied 2py to form a pi bond.
So, O2 has a double bond.
According to MOT,
the total number of electrons combine i.e.16 and the electronic configuration of O2 is written.
There is no triple bond in O2.
