• A. trans$-\left[ Fe \left( NH _{3}\right)_{2}( CN )_{4}\right]^{-}$
• B. cis$-\left[ Fe \left( NH _{3}\right)_{2}( CN )_{4}\right]^{-}$
• C. cis$-\left[\operatorname{Cr} Cl _{2}( ox )_{2}\right]^{3-}$( $ox =$ oxalate)
• D. trans$-\left[\operatorname{Cr}\left( Cl _{2}\right)( ox )_{2}\right]^{3-}$

Answer 1

Answer: (C)
