Answer» Correct Answer - A::B::C::D Oxidation state of CMI (central metal ion) can be calculated by considering the oxidation state of whole molecule is equal to charge present on coordination sphere. A. `[Co(NCS)(NH_(3))_(5)]SO_(3)`. Let oxidation state of `Co` is x. `x-1+5xx0= +2` `x= +2 +1= + 3` B. `[Co(NH_(3))_(4)Cl_(2)]SO_(4)` Let oxidation state of `Co=x` `rArr" "x+4xx0+2xx(-1)=+2` `rArr" "x-2=+2` `x=4` C. `Na_(4)[Co(S_(2)O_(3))_(3)]` Let oxidation state of `Co=x` `x+3xx(-2)=-4` `x-6= -4` `x=-4 +6=+2` D. `[Co(CO)_(8)]` Let oxidation state of `Co=x` `x-8xx0=0` `x=0` Hence, correct choice is (d).
