JEE Main 28 June 2022, Shift 1, Chemistry Q67

Question 67 of 90 in this shift, Chemistry question 7 of 30, Section A.

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 :
  1. (1)Both Statement I and Statement II are true.
  2. (2)Both Statement I and Statement II are false.
  3. (3)Statement I true, but statement II is false.
  4. (4)Statement I is false but statement II is true.Official answer
