(a)
Write the IUPAC name of the following complex : \[\mathrm{K}_{3}\left[\mathrm{Cr}\left(\mathrm{C}_{2} \mathrm{O}_{4}\right)_{3}\right] \]
(b)
Differentiate between homoleptic complex and heterolyptic complex.
(c)
Which type of isomerism is exhibited by the following complex : \[\left[\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{2} \mathrm{Cl}_{2}\right] \]
Marking-scheme solution
(a)
Potassium trioxalatochromate (III)
(b)
Complexes in which a metal is bound to only one kind of donor groups are called
homoleptic complexes whereas in heteroleptic complex the metal is bound to more
than one kind of donor groups.
(c)
Geometrical isomerism /cis-trans isomers.
