Question

The number of isomers possible for $\left[{\mathrm{Pt}}_{\left(\mathrm{en}\right)}{\left({\mathrm{NO}}_2\right)}_2\right]$ is:

• A. $2$
• B. $3$
• C. $4$
• D. $1$

Answer 1

The correct option is B

$3$

B:$3$

Isomers:

• In chemistry, isomers are molecules or poly-atomic ions with the same number of atoms in each element as their molecular formulas, but different configurations of atoms in space.
• Isomerism is the possibility or presence of isomers. Isomers don't always have the same chemical or physical characteristics.

Isomers of $\left[{\mathrm{Pt}}_{\left(\mathrm{en}\right)}{\left({\mathrm{NO}}_2\right)}_2\right]$:

• The $\left[{\mathrm{Pt}}_{\left(\mathrm{en}\right)}{\left({\mathrm{NO}}_2\right)}_2\right]$ neither show the optical isomerism nor the G.I.

• The $\left[{\mathrm{Pt}}_{\left(\mathrm{en}\right)}{\left({\mathrm{NO}}_2\right)}_2\right]$ posses three linkage isomers. These are $\left[{\mathrm{Pt}}_{\left(\mathrm{en}\right)}{\left({\mathrm{NO}}_2\right)}_2\right]$,$\left[{\mathrm{Pt}}_{\left(\mathrm{en}\right)}{\left(\mathrm{ONO}\right)}_2\right]$ and $\left[{\mathrm{Pt}}_{\left(\mathrm{en}\right)}\left({\mathrm{NO}}_2\right)\left(\mathrm{ONO}\right)\right]$.
