The species which is not paramagnetic among the following isA. `Cl^-`B. `Be`C. `Ne^(2+)`D. `As^+` |
|
Answer» Correct Answer - A Paramagnetic character is based upon presence of unpaired electron. `.17Cl^(-)=1s^2 , 2s^2 2p^6, 3s^2 3p_x^2 3p_y^2 3p_z^2` In `Cl^-` no unpaired electron , so it is in nature diamagnetic `._4Be=1s^2 , 2s^1 2p_x^1` `._10Ne^(2+)=1s^2 , 2s^2 2p_x^2 2p_y^1 2p_z^1` `._33As^(+)=1s^2, 2s^2 2p^6 , 3s^2 3p^6 3d^10 , 4s^2 4p_x^1 4p_y^1 4p_z^0` While all others have unpaired electron, so they are paramagnetic in nature. |
