Question:
Anhydrous $ {AlCl_3}$ is prepared from
Anhydrous $ {AlCl_3}$ is prepared from
Updated On: Jul 6, 2022
- conc. HCl and aluminium metal
- aluminium and $\ce{Cl_2}$
- dry HCl gas + heated aluminium metal
- none of above
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
When dry hydrochloride gas is passed over heated aluminium metal, then anhydrous aluminium chloride is obtained.
$ {$\underset{\text{(Dry)}}{ {HCl(g)}}$ + $\underset{\text{(Heated)}}{ {Al}}$ -> Anhydrous \, AlCl3 }$

Concepts Used:
P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
