Answer:
Explanation:
AlCl₃ forms a dimer in vapor state in order to compensate for the insufficient number of electrons that will make it attain stability in its structure.
Dimerization is a situation in which a molecule of a compound is derived from two identical monomers.
- Dimerization yields very weak/strong intermolecular interaction producing some chemical bonds.
- In the monomeric state, AlCl₃ does not have a complete octet.
- When in the vapor state, they attach to one another to compensate for this deficiency to attain stability.
