Isomorphism is exhibited by
- A
Molecular crystals
- B
Covalent solids
- C
Ionic Crystals
- D
Metallic solids
Isomorphism is exhibited by ionic crystal. As the crystals are similar in shape and the forces within and between molecules and ions are approximately similar and as a result the ionic crystal have same internal structure.Example are sodium nitrate and calcium citrate.
Molecular crystals: Molecular crystals are formed by weak intermolecular forces between discrete molecules, and they generally do not exhibit isomorphism. Isomorphism is more commonly observed in compounds with an ionic nature rather than molecular crystals.
Covalent solids: Covalent solids are formed by strong covalent bonds between atoms, and they do not typically exhibit isomorphism. Isomorphism is more commonly seen in compounds with an ionic nature rather than covalent solids.
This option is correct because isomorphism is exhibited by ionic crystal. As the crystals are similar in shape and the forces within and between molecules and ions are approximately similar and as a result the ionic crystal have same internal structure.Example are sodium nitrate and calcium citrate.
Metallic solids: Metallic solids are formed by a lattice of metal atoms surrounded by a sea of delocalized electrons, and they generally do not exhibit isomorphism. Isomorphism is more commonly observed in compounds with an ionic nature rather than metallic solids.
