Which of the following statements is correct?

(i) In the formation of dioxygen from oxygen atoms 10 molecular orbitals will be formed.


(ii) All the molecular orbitals in the dioxygen will be completely filled.


(iii) Total number of bonding molecular orbitals will not be same as total number of anti bonding orbitals in dioxygen.


(iv) Number of filled bonding orbitals will be same as number of filled anti bonding orbitals


(i)

Two molecular orbitals in the dioxygen have unpaired electrons.


Thus, statement (ii) is incorrect.


The total number of bonding molecular orbitals is the same as the total number of antibonding orbitals in dioxygen.


Thus, the statement (iii) is incorrect.


The number of filled bonding orbitals will not be always the same as a number of filled antibonding orbitals.


Thus, the statement (iv) is incorrect.


Thus, statement (i) is correct i.e. in the formation of dioxygen from oxygen atoms 10 molecular orbitals will be formed.
