Given below are two statements :
Statement -I : The pentavalent oxide of group- 15 element. E 2 O 5 . is less acidic than trivalent oxide.E 2 O 3 . of the same element.
Statement -II : The acidic character of trivalent oxide of group 15 elements. E 2 0 3 . decreases down the group.
choose most appropriate answer from the options given below :
Text Solution
Verified by ExpertsD
As +ve oxidation state increases, EN of element increases hence acidic character increases. Down the group, non-metallic character decreases, acidic character decreases. Acidic character : E 2 O 5 > E 2 O 3 Down the group, acidic character of E 2 O 3 decreases
