Q

which one is more soluble in diethyl ether? anyhdrous AlCl3 or Hydrious AlCl3

A

Anhydrous AlCl3 is more soluble in Diethyl ether as ether has electron pairs which can be acccomadated in the vacent orbitals of the Al(anyhydrous)
in hydrous one, the vacant orbitals are occupied by the electron pairs of H2O
