$ Al_2O_3$ can be converted into anhydrous $AlCl_3$ by heating
Updated On: Apr 17, 2024
- $ Al_2O_3$ with HCI gas
- $ Al_2O_3$ with NaCI in solid state
- $ Al_2O_3$ a mixture of $ Al_2O_3$ and carbon in dry $ Cl_2$ gas
- $ Al_2O_3$ with $ Cl_2$ gas
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$ Al_2O_3$ may be converted into anhyd. $AlCl_3$ by heating a mixture of $ Al_2O_3$ and carbon in dry chlorine.
$ Al_2O_3 + 3C + 3Cl_2 \longrightarrow Al_2Cl_6 $ $22\,mm$ Hot and dry $8\,mm$ Anhy $AlCl_2$
$ Al_2O_3 + 3C + 3Cl_2 \longrightarrow Al_2Cl_6 $ $22\,mm$ Hot and dry $8\,mm$ Anhy $AlCl_2$

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
