Question

b) whether oxide of element is ? i) acidic ii) basic iii) neutral iv) none​

Answer 1

Answer:

1. B2O3
2. All oxides in Group 1 & 2 elements are basic (except BeO)
3. carbon monoxide (CO); nitrous oxide (N2O); nitric oxide (NO), etc., are neutral oxides.
4. carbon monoxide (CO); nitrous oxide (N2O); nitric oxide (NO), etc., are neutral oxides.

Explanation:

1. In general, the electropositive character of the oxide's central atom will determine whether the oxide will be acidic or basic. The more electropositive the central atom the more basic the oxide. The more electronegative the central atom, the more acidic the oxide. B2O3 is the acidic oxide. On moving down the group 13, the nature of oxide changes from acidic to basic.
2. All oxides in Group 1 & 2 elements are basic (except BeO), they react with water to form a base: Lithium oxide reacts with water to produce Lithium hydroxide: Li2O(s) + H2O(l) → 2 Li+(aq) + 2 OH−(aq) Sodium oxide reacts with water to produce Sodium hydroxide: Na2O(s) + H2O(l) → 2 NaOH(aq)
3. Neutral oxides show neither basic nor acidic properties and hence do not form salts when reacted with acids or bases, e.g., carbon monoxide (CO); nitrous oxide (N2O); nitric oxide (NO), etc., are neutral oxides.
4. Neutral oxides show neither basic nor acidic properties and hence do not form salts when reacted with acids or bases, e.g., carbon monoxide (CO); nitrous oxide (N2O); nitric oxide (NO), etc., are neutral oxides.
