Reactivity Towards Oxygen Chemistry Notes

Reactivity Towards Oxygen :

The elements of nitrogen family generally forms two types of oxides i.e., trioxides (E<sub>2</sub>O<sub>3</sub>) and pentoxides (E<sub>2</sub>O<sub>5</sub>) Nitrogen form a large number of acids from + loxidation state to + 5 oxidation state. It is because of large tendencey of nitrogen to form pπ – pπ multiple, bonds with oxygen. The oxides formed by various elements of group-15 are listed in table 7.5

Reactivity Towards Oxygen Chemistry Notes 1

As we know that oxides of non-metal are acidic, while those of metalloids are amphoteric and those of metals are basic in nature. As electronegativity of the element increases, the acidic nature of oxides increases.

Furthermore as oxidation no. of element increases their acidic behaviour increases. Hence, we can arrange the oxides on the basis of acidic strength as follows
