Answer» Correct Answer - D Molecular orbitals electronic configuration of `O_(2)` is `(sigma1s)^(2)(sigma^(**)1s)^(2)(simga2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(z))^(2)(pi2p_(x))^(2)(pi 2p_(y))^(2)(pi 2p_(y))^(2)(pi^(**)2p_(x))^(1)(pi^(**)2p_(y))^(1)` `:. B.O. ` of `O_(2)=1/2 (10-6)=2` Molecular orbitals electronic configuration of `O_(2)^(+)` is `(sigma1s)^(2)(sigma^(**)1s)^(2)(sigma2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(z))^(2)(pi 2p_(x))^(2)(pi 2p_(y))^(2)(pi^(**)2p_(x))^(1)` `:. B.O. ` of `O_(2)^(+) =1/2 (10-5) =2.5` Molecular orbitals electronic configuration of `O_(2)^(-)` is `(sigma1s)^(2)(sigma^(**)2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(z))^(2)(pi 2p_(x))^(2)(pi2p_(y))^(2)(pi^(**)2p_(x))^(2)(pi^(**)2p_(x))^(2)(pi^(**)2p_(y))^(1)` `:. B.O.` of `O_(2)^(-)=1/2 (10-7) =1.5` molecular orbitals electronic configuration of `O_(2)^(2-)` is `(sigma1s)^(2)(sigma^(**)1s)^(2)(sigma2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(z))^(2)(pi 2p_(x))^(2)(pi2p_(y))^(2)(pi^(**)2p_(x))^(2)(pi^(**)2p_(y))^(2)` `:. B.O.` of `O_(2)^(2-) =1/2(10-8)=1.0` `:.` increasing order of B.O. is `O_(2)^(2-) gt O_(2)^(-) gt O_(2) gt O_(2)^(+)` |
