Match List-I with List-II. List-I (Molecule) (A) KO3 (B) H2O2 (C) MgO (D) KO2 List-II (Oxidation state of oxygen) (I) –1 (II) –1/3 (III) –1/2 (IV) –2 Choose the correct answer from the options given below:
A
A-II, B-IV, C-III, D-I
B
A-I, B-II, C-IV, D-III
C
A-II, B-I, C-IV, D-III
D
A-III, B-IV, C-I, D-II
Explanation
KO3 : x = –1/3 H2O2 : x = –1 MgO : x = –2 KO2 : x = –1/2
