What is the Difference Between Isomorphism and Polymorphism?
🆚 Go to Comparative Table 🆚Isomorphism and polymorphism are two terms used to describe the external appearances of chemical substances, specifically their crystal structures. Here are the main differences between the two:
- Similarity: Isomorphism refers to the similarity in the crystal structure of different compounds, while polymorphism refers to the presence of different crystalline forms of the same compound.
- Shape: Isomorphic compounds have identical shapes, whereas polymorphic substances have different shapes.
- Compound: Isomorphism concerns two or more different compounds, while polymorphism describes the different forms of the same compound or element.
- Elements: Isomorphism cannot be observed in elements, while polymorphism can be observed in elements.
- Atomic Ratio: The atomic ratios of isomorphous compounds are the same, while the atomic ratios of polymorphic compounds may or may not be the same.
In summary, isomorphism refers to the presence of two or more compounds with identical morphologies, while polymorphism refers to the presence of different morphologies of the same substance.
Comparative Table: Isomorphism vs Polymorphism
The main difference between isomorphism and polymorphism is that isomorphism describes the similarity in the crystal structure of different compounds, while polymorphism refers to the presence of different crystalline forms of the same compound. Here is a comparison table highlighting the key differences between isomorphism and polymorphism:
Feature | Isomorphism | Polymorphism |
---|---|---|
Definition | Similarity in crystal structure of different compounds | Presence of different crystalline forms of the same compound |
Shape | Identical shapes of isomorphous substances | Different shapes of polymorphic substances |
Compound | Two or more different compounds have identical morphologies | Same compound or element exists in different morphologies |
In summary, isomorphism refers to the presence of two or more compounds with identical morphologies, while polymorphism refers to the presence of different morphologies of the same substance.
