Which one of the following pairs consists of only paramagnetic speciesA. `O_2, NO`B. `O_2^(+)`,`O_2^(2-)`C. `CO, NO`D. `NO, NO^(+)` |
|
Answer» Correct Answer - A `O_2^(2-)(18e^(-)s)`, `CO(14 e^(-)s)`, and `NO^(+)(14e^(-)s)` are diamagnetic while `O_2(16e^(-)s)`, `NO(15e^(-)s)`, `O_2^(+)(15e^(-)s)`, and `N_2^(-)(13e^(-)s)` are paramagnetic. Note that `O_2` is unusual as it is an even electron molecule but has `2` unpaired electrons. |
