Vedclass · Answer

(B) $1$. Identify the ligands: The complex contains two fluoride ions $(F^-)$ and two ethylenediamine $(en)$ molecules. The ligand $F^-$ is named 'fluorido' and $en$ is named 'ethane$-1,2-$diamine'.$2$. Determine the order: Ligands are named in alphabetical order. 'Ethane$-1,2-$diamine' starts with 'e' and 'fluorido' starts with 'f'. Since there are two of each,we use the prefix 'bis' for the bidentate ligand $en$ and 'di' for $F^-$.$3$. Oxidation state of central metal: Let the oxidation state of $Cr$ be $x$. The charge on $F$ is $-1$ and $en$ is $0$. The total charge of the complex $[CrF_2(en)_2]^+$ is $+1$ (since $Cl$ is $-1$). So,$x + 2(-1) + 2(0) = +1$,which gives $x = +3$.$4$. Assemble the name: The name is 'difluoridobis(ethane$-1,2-$diamine)chromium$(III)$ chloride'. Among the given options,'difluoridobis(ethylene diamine) chromium$(III)$ chloride' is the standard nomenclature representation.
