Question
K6[(CN)5 CO - O - O - CO(CN)5] 
K5[(CN)5Co - O - O - Co(CN)5]
(X) (Y)
In both the complexes Co have t2g6eg0 configuration.
The bond energy of (O - O) in X and Y is :
K5[(CN)5Co - O - O - Co(CN)5](X) (Y)
In both the complexes Co have t2g6eg0 configuration.
The bond energy of (O - O) in X and Y is :
Options
A.bond energy of (O - O) in Y < bond energy of (O - O) in X.
B.bond energy of (O - O) in X < bond energy of (O - O) in Y.
C.bond energy of (O - O) in X = bond energy of (O - O) in Y.
D.bond energy of (O - O) in X and bond energy of (O - O) in Y can′t be comparable.
Solution
K6[(CN-5)5 Co (III) - O - O - Co (III) (CN-5)5]6+ 
K5[(CN-5)5 Co - O-1 - Co(CN-5)5]5+.
O22-
O2- ; bond order of O22- = 
= 1; bond order of O2- = 
= 1.5
Bond strength ∞ bond order ; so,
Bond energy of O22- < Bond energy of O2-.
K5[(CN-5)5 Co - O-1 - Co(CN-5)5]5+.O22-
O2- ; bond order of O22- = = 1; bond order of O2- = = 1.5Bond strength ∞ bond order ; so,
Bond energy of O22- < Bond energy of O2-.
