Vedclass · Answer

(A) The basic character of oxides depends on the nature of the element forming the oxide.$1$. $NO_2$ is a non-metallic oxide,which is acidic in nature.$2$. $ZnO$ is an amphoteric oxide,which shows both acidic and basic properties.$3$. $K_2O$ is a metallic oxide,which is strongly basic in nature.Therefore,the order of increasing basic character is: $	ext{Acidic oxide} Thus,the correct order is: $NO_2 < ZnO < K_2O$.

Arrange the following in the order of increasing basic character: $(NO_2, K_2O, ZnO)$
