Question

Would you please help me with this question .Show how aluminium chloride exists as a dimer.Thanks in advance.

Answer 1

Answer:

To get to the very favorable 8 electron octet, it forms Al2Cl6 and thus the extra sharing from the dimer gives the necessary octet for all atoms. Aluminium chloride is electron deficient so it is very unstable . So, AlCl3 achieves stability by forming a dimer
