Question

AlCl3 behaves like a lewis acid. substantiate this statement. ​

Answer 1

Answer:

In AlCl3, it forms three bonds and hence outer shell has 6 electrons. In AlCl3, Al needs two electron to complete its octet so it needs electron from outside and it exist in dimer form and form bond with Cl atom and complete its octet so its accept non bonding electron pair from Cl so we called it lewis acid.

Answer 2

Answer:

In AlCl3 , Al in electron deficient it needs two electrons to complete octet so it act as lewis acid. AlCl3 usually exist as a dimer to achieve octet by bridged Cl atom electron deficient compounds are lewis acids.
