Which of the following statements about anhydrous aluminium chloride is correct?

AIt exist as $$AlCl_{3}$$ molecule
BIt is a strong lewis base
CIt sublimes at $$100^{0}C$$ under vaccum
DNone of the above.
Correct Answer

Solution

Anhydrous aluminium chloride is white solid and it exists as $$Al_2Cl_6$$. It is electron deficient compound and so acts as strong Lewis acid. It sublimes when heated at $$180^oC$$. So none of the above statements is correct.
