Question

Discuss the structures of halides.

Answer 1

1. Halides are compounds formed between halogens and other elements.
2. They can be ionic or covalent depending on the elements involved.
3. Ionic halides form between metals and halogens with high melting points.
4. Covalent halides form between non-metals and halogens with discrete molecules.
5. Structures of halides depend on the nature of bonding and size of atoms.
6. For example, alkali metal halides have a simple cubic lattice (NaCl type).
7. Some halides show molecular structures with tetrahedral or octahedral shapes.
8. Hydrogen halides are simple diatomic molecules (HX).
9. Interhalogen compounds have structures like linear, T-shaped, or square pyramidal.
10. Noble gas halides have distorted octahedral or square pyramidal structures.
