Chemistry - Coordination Chemistry Question with Solution | TestHub
Consider following two complexes and select CORRECT statements and
(a) Both are isomers.
(b) Both have two chelate rings.
(c) Both produce the same mass of precipitate with excess .
(d) Both are heteroleptic complexes.
Options:
Answer:
Solution:
The complexes and are ionization isomers because they exchange ligands between the coordination sphere and the counter-ions. Both are heteroleptic as they contain different types of ligands ( and or ) and both possess two chelate rings formed by the bidentate ethylenediamine () ligands. However, they do not produce the same mass of precipitate with excess because one yields moles of (molar mass ) while the other yields moles of (molar mass ). Thus, statements (a), (b), and (d) are correct, making Option (B) the right choice.
