FAQs on Structural & Linkage Isomerism

Question 1

1. What is structural isomerism?

Accepted Answer

Ans. Structural isomerism refers to the phenomenon in which molecules have the same molecular formula but differ in the arrangement of atoms within the molecule. This difference in the arrangement of atoms gives rise to different structural isomers.

Question 2

2. What is linkage isomerism?

Accepted Answer

Ans. Linkage isomerism is a type of structural isomerism in coordination compounds. It occurs when the same ligand can coordinate to the central metal atom through different atoms. This results in the formation of different compounds with different properties.

Question 3

3. How can one identify structural isomers?

Accepted Answer

Ans. Structural isomers can be identified by comparing the connectivity of atoms in different molecules. If the arrangement of atoms is different, then the molecules are structural isomers. Physical and chemical properties, as well as spectroscopic techniques, can also be used to differentiate between structural isomers.

Question 4

4. Give an example of structural isomerism.

Accepted Answer

Ans. An example of structural isomerism is the isomers of butane. Butane has the molecular formula C4H10. There are two structural isomers of butane: n-butane and isobutane. In n-butane, the carbon atoms are arranged in a straight chain, while in isobutane, the carbon atoms are arranged in a branched chain.

Question 5

5. How does linkage isomerism affect the properties of coordination compounds?

Accepted Answer

Ans. Linkage isomerism can have a significant impact on the properties of coordination compounds. Since different atoms are involved in the coordination, the geometry around the central metal atom may change, leading to different physical and chemical properties. For example, the color of a coordination compound may change due to the presence of different ligands in linkage isomers.
