Stereoisomerism occurs when the bond connectivity is same but the spatial arrangement of more than one type is possible. Stereoisomerism finds vast use in orgaic chemistry, mainly biochemistry as all the biomolecules, are generally stereospecific in their actions. Stereoisomerism in limited not only to organic compounds but also to anorganic compounds, mainly in co-ordination complexes. Stereoisomers include cis and trans isomers, chiral isomers, compound wilth different conformation of chelate rings and other isomers that differ only in the geometry of attachement of the metal ion.
Select the incorrect statement:

Options

A. trans from of `[CoCl_(2)("trien")]^(+)` has 3 coplanar chelate ring
B. `[Pt(py)(NH_(3))(NO_(2))(Cl)(Br)(I)]` has 15 geometrical isomers
C. Carboxylic group of salicylate ion is cis and tans to tertiary nitorgen in `[Co("tren")("sal")]^(+)`
D. `[Pt(NH_(3))_(2)(py)_(2)Cl(2)]^(2+)` complex has 5 non chiral isomer.

Answer

D

Explanation

`[Pt(NH_(3))_(2)(py)_(2)Cl_(2)]^(2+)` has 4 non chiral isomer.
