Vedclass · Answer

(C) $1$. The name $dibromidobis(ethylenediamine)chromium(III)$ bromide indicates the following components: $2$. $Chromium(III)$ is the central metal ion: $Cr^{3+}$. $3$. $Bis(ethylenediamine)$ means two $en$ ligands: $(en)_2$. $4$. $Dibromido$ means two $Br^-$ ligands: $Br_2$. $5$. The coordination sphere is $[Cr(en)_2Br_2]$. $6$. The oxidation state of $Cr$ is $x + 2(0) + 2(-1) = +1$ (for the whole complex),so $x - 2 = +1$,$x = +3$. $7$. The counter ion is $Bromide$ $(Br^-)$,which balances the $+1$ charge of the complex. $8$. Thus,the formula is $[Cr(en)_2Br_2]Br$.

Which of the following has the name $dibromidobis(ethylenediamine)chromium(III)$ bromide?
