Generally,a group of atoms can function as a ligand if:

The ligand present in lithium tetrahydroaluminate is........

Potassium cyanide is made alkaline with $NaOH$ and boiled with thiosulphate ions. The solution is cooled and acidified with $HCl$ and this solution with iron $(III)$ chloride produces :-

Primary and Secondary valency of $Co$ in the complex compound $[Co(en)_3]Cl_3$ is respectively . . . . . . .

Given the molecular formulas of the hexa-coordinated complexes: $(a)$ $CoCl_3 \cdot 6NH_3$,$(b)$ $CoCl_3 \cdot 5NH_3$,$(c)$ $CoCl_3 \cdot 4NH_3$. If the number of coordinated $NH_3$ molecules in $(a)$,$(b)$,and $(c)$ are $6, 5$,and $4$ respectively,the primary valencies in $(a)$,$(b)$,and $(c)$ are:

The types of bonds present in ${K_4}[Fe(CN)_6]$ are:
