Chemistry - Coordination Chemistry Question with Solution | TestHub
An aqueous solution of salt (P) gives a white precipitate with Barium chloride solution, which is insoluble in dilute HCl and dilute HNO₃. When aqueous ammonia is added to the aqueous solution of salt (P), a blue precipitate is obtained, which dissolves in excess ammonia, producing a deep blue coloration due to the formation of complex (Q). With KCN, (P) first gives a yellow precipitate, which quickly decomposes to a white precipitate along with liberating a highly poisonous gas (R). (R) on hydrogenation produces (S), which gives a yellowish-orange colored complex (T) with CoCl₃.
Which of the following options is correct with respect to and T .
Options:
Answer:
Solution:
Salt (P) is , as it forms a white precipitate and a deep blue complex, (Q), with ammonia.
Reaction with yields a yellow precipitate that decomposes to release poisonous cyanogen gas (R).
Hydrogenation of cyanogen (R) produces ethylenediamine (), which is substance (S).
Since ethylenediamine is a bidentate ligand, option (B) is the correct choice.
