A) 2.5
B) 2
C) 1.5
D) 1
Correct Answer: C
Solution :
The MO configuration of superoxide ion, \[\{O_{2}^{-}(8+8+1=7)=\sigma 1{{s}^{2}},\overset{*}{\mathop{\sigma }}\,1{{s}^{2}},\sigma 2{{s}^{2}},\]\[\overset{*}{\mathop{\sigma }}\,2{{s}^{2}},\sigma 2p_{z}^{2},\pi 2p_{x}^{2}\approx \pi 2p_{y}^{2}\overset{*}{\mathop{\pi }}\,2p_{x}^{2}\approx \overset{*}{\mathop{\pi }}\,2p_{y}^{1}\}\] \[B.O.=\frac{{{N}_{b}}-{{N}_{a}}}{2}=\frac{10-7}{2}=\frac{3}{2}=1.5\]
