Question

Which of the following statement(s) is/are incorrect

Options

A.In [CoBrCl(en)2]+ geometrical isomerism exists, while optical isomerism does not exist
B.

Potassium aquadicyanidosuperoxidoperoxidochromate(III) is IUPAC name for

K2[Cr(CN)2O2(O2)(H2O)]

C.

There are 3 geometrical isomers and 15 stereoisomers possible for

[Pt(NO2)(NH3)(NH2OH)(py)]+ and [PtBr ClI (NO2)(NH3)(py)] respectively

D.cis and trans forms are not diastereomers to each other

Solution

Sol. (A) [COBrCl(en)2]+

(B) K2[Cr(CN)2O2(O2)(H2O)]

Potassium aquadicyanidosuperoxidoperoxidochromate (II)

(C) [Pt(NO2)(NH3)(NH2OH)(Py)]+ ⇒ 3-geometrical isomers

[PtBrCl I(NO2)(NH3)(Py)] ⇒ 30-stereoisomers

(D) cis and Trans are diastereo-isomers.
