(a) What is the number of molecular orbitals obtained by mixing of two atomic orbitals ?
(b) Out of `F_(2)` and `OF` which of these molecules is (are) paramagnetic

Explanation

Two
(b) `OF` is paramagnetic since it has one unpaired antibonding electron
(c ) `NO^(o+)` has lost an antibonding electron Whereas `CO^(o+)` has lost a bonding electron
(d) It should be stabel because it has one more bonding electron the antibonding .
