  • a)
    Ionization isomerism
  • b)
    Linkage isomerism
  • c)
    Geometrical isomerism
  • d)
    Coordination isomerism
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The existence of two different coloured complexes with the composition...
Complexes of [MA4B2] type exhibit geometrical isomerism.

The complex [Co(NH3)4Cl2]+ is a [MA4B2] type complex and thus, fulfils the conditions that are necessary to exhibit geometrical isomerism. Hence, it has two geometrical isomers.

Explanation:

The given complex is [Co(NH3)4Cl2]. This complex is known for its geometrical isomerism.

Geometrical isomerism is a type of stereoisomerism where two or more compounds have the same molecular formula and same connectivity but differ in the orientation of their atoms or groups in space.

In the given complex, the two Cl atoms can either be adjacent to each other or opposite to each other. These two different arrangements of Cl atoms give rise to two different isomers of the complex, which are known as cis-[Co(NH3)4Cl2] and trans-[Co(NH3)4Cl2].

In cis-[Co(NH3)4Cl2], the two Cl atoms are adjacent to each other, and in trans-[Co(NH3)4Cl2], the two Cl atoms are opposite to each other.

Hence, the existence of two different coloured complexes with the composition of [Co(NH3)4Cl2] is due to geometrical isomerism.

geometrical isomerism

Complexes of [MA4B2] type exhibit geometrical isomerism.

The complex [Co(NH3)4Cl2]^+ is a [MA4B2] type complex and thus, fulfils the conditions that are necessary to exhibit geometrical isomerism. Hence, it has two geometrical isomers
