  • question_answer
    In which of the following ionization processes the bond energy has increased and also the magnetic behaviour has changed from paramagnetic to diamagnetic?

    A) \[NO\to N{{O}^{+}}\]    

    B) \[{{N}_{2}}\to N_{2}^{+}\]

    C) \[{{C}_{2}}\to {{C}_{2}}^{+}\]        

    D) \[{{O}_{2}}\to {{O}_{2}}^{+}\]

    Correct Answer: A

    Solution :

    [a] For NO Total no. of electrons =15 \[B.O=2.5\] Mag. Behaviour = Paramagnetic For \[N{{O}^{+}}\] Total no. of electrons = 14 B.O=3 Mag. Behaviour = Diamagnetic
