Given below are two statements :
Statement I : The pentavalent oxide of group-15 element, E2O5, is less acidic than trivalent oxide, E2O3, of the same element.
Statement II : The acidic character of trivalent oxide of group 15 elements, E2O3, decreases down the group.
In light of the above statements, choose most appropriate answer from the options given below :
Solution
As +ve oxidation state increases, EN of element
increases hence acidic character increases. Down
the group, non-metallic character decreases, acidic
character decreases.<br/><br/>
Acidic character : E<sub>2</sub>O<sub>5</sub> > E<sub>2</sub>O<sub>3</sub><br/><br/>
Down the group, acidic character of E<sub>2</sub>O<sub>3</sub> decreases.
