Report Error
A
If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:
B
If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:
C
If Assertion: is true but Reason: is false
D
If both Assertion: and Reason: are false
Solution:
CO
is a neutral ligand, thus oxidation state of
F
e
in
F
e
(
CO

5
is
