Ques. 1AIPMT 2006

[Co(NH3)4(NO2)2]Cl exhibits

  1. linkage isomerism, geometrical isomerism and optical isomerism
  2. linkage isomerism, ionization isomerism and optical isomerism
  3. linkage isomerism, ionization isomerism and geometrical isomerism
  4. ionization isomerism, geometrical isomerism and optical isomerism.

Answer

(3) linkage isomerism, ionization isomerism and geometrical isomerism

Solution

Linkage isomerism: NO2- is ambidentate (bonds through N as nitrito-N or through O as nitrito-O) ⇒ shown.

Ionization isomerism: Cl- outside and NO2- inside can interchange, e.g. [Co(NH3)4(NO2)Cl]NO2 ⇒ shown.

Geometrical isomerism: octahedral [MA4B2] type ⇒ cis and trans forms ⇒ shown.

Optical isomerism: both cis and trans forms of [MA4B2] have a plane of symmetry ⇒ not shown.

∴ The complex exhibits linkage, ionization and geometrical isomerism.

Answer: (3)
