The solid HCl is composed of molecules held together by intermolecular dipole–dipole interactions. The significant **electronegativity **difference between H and Cl make the dipole -dipole force in between HCl molecules.
What is dipole - dipole force ?
**Dipole -dipole forces **arises between molecules of permanent dipole moment. Covalent compounds are formed between two non-metals through electron sharing .
When one atoms is highly electronegative compared to the other, the shared pair of electrons attracts more to the electronegative atom. Which make partial charge separation and the compound becomes polar .
Two polar molecules attracts each other through dipole -dipole forces. **HCl **is a polar compound. Thus, in HCl solid, HCl molecules are held together by dipole -dipole forces.

Solid HCl is composed of molecules held together by intermolecular dipole-dipole interactions. As a polar molecule, HCl has partial charges that attract neighboring molecules. This type of interaction is weaker than ionic bonding but is significant in molecular solids like HCl.
