(a) Write the IUPAC name and hybridisation of the complex [CoF_(6)]^(3-). [Given : Atomic number of Co = 27] (b) What type of isomerism is shown by the complex [Co(en)_(2)Cl_(2)]^(2+) ? Name the structure of an isomer of this complex which is optically active.

Answer»

Solution :(a) IUPAC NAME : Hexachloridocobaltate (III) ion.
(b) GEOMETRICAL isomerism is SHOWN by `[CO(en)_(2)Cl_(2)]^(2+)`.
cis - `[Co(en)_(2)Cl_(2)]^(2+)` is optically active.
