Question

Explain the chenical reactivity of group 13 elements.

Answer 1

combustion is the chemical reactivity of group 13elements

Answer 2

The chemical reactivity of the group 13 elements are as follows:

1. Reactivity with air – In the crystalline form, Boron is unreactive. Whereas aluminum on reaction with air forms a thin layer of oxide. When boron is taken in amorphous form and heated, it forms B2O3, and aluminium on heating forms Al2O3..  

2.Reactivity with acids and alkalis – Aluminium being amphoteric in nature dissolves in both acids and alkalis. Boron does not react with acids or alkalis.

3. Reactivity with halogens – These elements on reacting with halogens form trihalides (Tl and I3 are exceptions in this case).
