Give name ofthe complex, name should specify the position of ligands.

Options

A. bistransphosphinecarbonylchloroiridium (II)
B. carbonylchlorobistransphosphineiridium (Ill)
C. carbonylchlorobistransphosphineiridium (I)
D. chlorocarbonylbistransphosphineiridium (I)

Answer

C

Explanation

naming should be done alphabetically. Hence, 'carbonyl' is followed bty 'chloro' and then 'phosphine' bis used to denote two same groups and trans denotes the position. 'CO', and `'PH_(3)'` are neutral ligands. Only `Cl^(-)` is charged.hence oxidation state of Ir is `(+I)` only. thus correct IUPAC name of given complex is carbonylchlorobistransphosphineiridium (l).
