Question

Count correct statements: (i) O₂⁻ has a longer bond than O₂⁺; (ii) increased metal→CO π back donation can strengthen M–C but weaken C–O; (iii) removing a weakly antibonding HOMO electron necessarily lowers bond order; (iv) N₂⁺ has lower BO than N₂; (v) peroxide has more unpaired electrons than superoxide.

TestHub · Accepted Answer

i follows BO1.5<2.5; ii is synergic back donation; iv removes a bonding electron. iii is false for an antibonding electron, and v reverses diamagnetic peroxide/paramagnetic superoxide. Count 3.
