Vedclass · Answer

(B) Let us analyze each option:$A$: The complex $[Co(NH_3)_5NO_2]_3 [Co(NO_2)_6]_2$ is named correctly as pentaamminenitrito-$N$-cobalt$(III)$ hexanitrito-$N$-cobaltate$(III)$.$B$: For $H_2[OsCl_5N]$,the oxidation state of $Os$ is $x + 5(-1) + (-3) = 0$,so $x = +8$. The name should be hydrogen pentachloridonitridoosmate$(VIII)$,not $(VI)$. Thus,this is incorrect.$C$: For $K_2[OsCl_5N]$,the oxidation state of $Os$ is $2(+1) + x + 5(-1) + (-3) = 0$,so $x = +6$. The name is correct.$D$: $[Cr(H_2O)_6]^{3+}$ is correctly named as hexaaquachromium$(III)$ ion.
