Among the following , the paramagnetic compound is :A. `N_2O`B. `Na_2O_2`C. `O_3`D. `KO_2` |
|
Answer» Correct Answer - D `N_2O(7+7+8=22)` and `O_3(3xx8=24)` contain even number of electrons which are all paired. `(Na^(+))_2(O_2^(2-))` contains peroxide ion which is diamagnetic. `K^(+)(O_2^(-))` contains superoxide ion which is paramagnetic `O_2^(-)impliessigma1s^2, sigma^**1s^2, sigma2s^2sigma^**2s^2sigma2p{:(pi2p_x^2,pi^**2p_x^2,,,),(pi2p_y^2,pi^**2p_y^1,,,):}` |
