Why does alcl3 form a dimer in vapour state

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.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
