In the vapor state, Aluminium chloride () exists as a dimer (). What is the hybridization of the Alu — p Block Elements Chemistry Question

💡 Solution & Explanation

In the $Al_2Cl_6$ dimer, each Aluminium atom forms three single covalent bonds with Chlorine and accepts one coordinate bond from a bridging Chlorine atom to complete its octet. This results in 4 electron domains and $sp^3$ hybridization.
