Which of the following molecular species has unpaired electrons(s) ? .A. `N_(2)`B. `F_(2)`C. `O_(2)^(-)`D. `O_(2)^(2-)` |
|
Answer» Correct Answer - C Only `O_(2)^(-)` contains unpaired electrons in antibonding molecular orbital. `(sigma1s)^(2)(sigma^(**)1s)^(2)(sigma2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(z))^(2)(pi 2p_(x))^(2)(pi 2p_(y))^(2)(pi^(**)2p_(x))^(2)(pi^(**)2p_(y))^(1)` This shows one unpaired electron. |
