    The molecule NO is

    A)  paramagnetic

    B)  diamagnetic

    C)  ferromagnetic

    D)  an even electron molecule

    Correct Answer: A

    Solution :

     The molecule NO is paramagnetic. There is a unpaired electron on the nitrogen and it is an odd electron molecule. Alternately we can say it is a free radical and hence is highly reactive. \[\bullet \overset{\bullet \,\bullet }{\mathop{\text{N}}}\,=\underset{\bullet \,\bullet }{\overset{\bullet \,\bullet }{\mathop{\text{O}{}_{\bullet }^{\bullet }}}}\,\]
