Al2O3 maybe converted to anyhydrous AlCl3 by heating of mixture of Al2O3 and carbon in dry chlorine. Al2O3+3C+ undersethot text and text dry mathop3Cl2 xrightarrow[] underset(anhydrous text AlCl3) mathopAl2Cl6 Note Anhydrous AlCl3 exists in the form of dimer as

Q. $A l_{2} O_{3}$ can be converted to anhydrous $A lC l_{3}$ by heating

$A l_{2} O_{3}$ with $H Cl$ gas

$A l_{2} O_{3}$ with $N a Cl$ in solid state

a mixture of $A l_{2} O_{3}$ and carbon in dry $C l_{2}$ gas

$A l_{2} O_{3}$ with $C l_{2}$ gas

$A l_{2} O_{3}$ maybe converted to anyhydrous $A lC l_{3}$ by heating of mixture of $A l_{2} O_{3}$ and carbon in dry chlorine. $A l_{2} O_{3} + 3 C + h o t an d d ry 3 C l_{2} (anh y d ro u s A lC l_{3}) A l_{2} C l_{6}$ Note Anhydrous $A lC l_{3}$ exists in the form of dimer as
