Oxidation state

Hi
I need help in this question.

a= oxidation state is +3
I don't know how we are supposed to work on b as I don't know what oxidation state of C
for c = I think oxidation state is -1
for d= oxidation state is +1

What is the charge on the ethanedioate ion?

What is the charge on the OH- group?

for a)
oxidation state of V is +3 as you said
:s-smilie:

for b)
what is the charge of an ethanedioate ion?
Then its a matter of solving an equation:
V + (3 * charge of ethanedioate ) = +3
:s-smilie:

for c)
charge of OH group?
then solve another equation:
V + (3 * charge of OH ligand) = 0
:s-smilie:

for d)
charge of chloride ligand?
V + (4 * charge of chloride ligand ) = -3

no oxidation state is +3 on a b and c but for d it is +1
