Diamagnetic species among the following is
(1) `O_(2)`
(2) `O_(2)^(-)`
(3) `O_(2)^(2-)`
(4) `O_(2)^(+)`

If 2s-2p mixing is not operative the diamagnetic species among the followng is/are H_(2),H_(2)^(+),Li_(2), B_(2), C_(2), N_(2), O_(2)^(-), F_(2)

The number of paramagentic species among the following is O_(2), CO, N_(2), C_(2), CsO_(2), BaO_(2), CO_(2)

Compare the relative stabilities and magnetic behaviour of the following species (a) O_(2)^(Θ) and N_(2)^(o+) (b) O_(2)^(2-) and N_(2)^(Θ) (c ) O_(2)^(2-) and N_(2)^(2-) .

Using molecular orbital theory predict the correct decreasing bond order of the following species 1. O_(2)^(+) 2. O_(2)^(-) 3. O_(2)^(2-) 4. O_(2)^(2+)

In the species O_(2) , O_(2)^(+) , O_(2)^(-) and O_(2)^(2-) ,the correct decreasing order of bond strength is (A) O_(2) > O_(2)^(+) > O_(2)^(-) > O_(2)^(2-) (B) O_(2)^(+) > O_(2) > O_(2)^(-) > O_(2)^(2-) (C) O_(2)^(2-) > O_(2)^(-) > O_(2)^(+) > O_(2) (D) O_(2)^(-) > O_(2)^(2-) > O_(2) > O_(2)^(+)

Find the number of species among the following which can exist. TiO_(2),VO_(2)^(+),CrO_(4)^(2-),MnO_(4)^(-),FeO_(4)^(2-),FeO_(4)^(2-),VO^(2+),TiO^(2+),Sc^(2)O_(3),Mn_(2)O_(7) .
