Question

Given below are two statements:

Statement I: The pentavalent oxide of group-15 element, E2O5\mathrm{E_2O_5}, is less acidic than trivalent oxide, E2O3\mathrm{E_2O_3}, of the same element. Statement II: The acidic character of trivalent oxide of group 15 elements, E2O3\mathrm{E_2O_3}, decreases down the group.

In light of the above statements, choose most appropriate answer from the options given below:

Options
  1. a

    Both Statement I and Statement II are true.

  2. b
