Vedclass · Answer

(B) The complex ion is $[Co(NH_3)_5 ONO]^{2+}$.$1$. The ligand $NH_3$ is named as 'ammine' and there are $5$ of them,so it is 'pentaammine'.$2$. The ligand $ONO^-$ is an ambidentate ligand attached through oxygen,named as 'nitrito-$O$'.$3$. The central metal atom is Cobalt $(Co)$.$4$. Let the oxidation state of $Co$ be $x$. The charge on $NH_3$ is $0$ and on $ONO$ is $-1$. The total charge is $+2$.$x + 5(0) + (-1) = +2 \implies x = +3$.$5$. Combining these,the $IUPAC$ name is pentaamminenitrito-$O$-cobalt$(III)$ ion.
