What are the similar properties in Beryllium and Aluminium? |
| Answer» SOLUTION :The similar PROPERTIES in Be and AI are: (a) Both Be and AI form covalent compounds EX: `BeCI_(2)` and `AICI_(3)` (b) Both Be and AI have same electronegativity (i.e., Be = 1.5, AI = 1.5 (c ) Both `BeCI_(2)` and `AICI_(3)` used as catalyst in Fridel - Craft.s reaction because both act as LEWIS acid. (d) Both Be and AI form an oxide coating . Hence, they donot react with water. (e ) Both `Be_(2)C` and `AI_(4)C_(3)` react with water to liberate methane gas. | |
