Question

Indicate the types of isomerism exhibited by the following complexes and draw the structures for these isomers:

• A. $K\left[Cr\right(H_{2}O{)}_2\left(C_2{O}_4{)}_2\right]$
• B. $\left[Co\right(en{)}_3]{Cl}_3$
• C. $\left[Co\right({NH}_3{)}_5\left({NO}_2\right)]({N{O}_3)}_2$
• D. $\left[Pt\right({NH}_3\left)\right(H_{2}O\left){Cl}_2\right]$

Answer 1

The correct option is A $K\left[Cr\right(H_{2}O{)}_2\left(C_2{O}_4{)}_2\right]$

$A$ - exhibits cis trans.

$B$- Exhibits optical Isomerism.

$C$- Exhibits linkage Isomerism $(N{O}_2,-ONO)$

$D$- Cis-Trans Isomerism.
