    Which of the following contains the maximum number of unpaired electrons?

    Which of the following contains the maximum number of unpaired electrons?

    The molecular orbital with the lowest eenrgy is filled first. Thus sigma (1s) is filled first where as 'sigma^(*)(2p) isfilled in thelast, also the maximum number of electron in bonding and antibonding molecular orbitals are according to Pauli and Hund's rule. As an electron in an antibonding molecular orbital cancels out the stability introduced by the electron in a bonding molecular orbital, it means that in order for bonding of atoms to occur there should be an excess of bonding electron sover antibonding electrons. In case where the number of bonding and antibonding electrons are equal, no bond will be formed between the atoms. With the help of above discussion, we can define easily bond order, relative bond length, relative stability and magnetic properties for a molecule. Which of the following are paramagnetic in nature ?
