Fusion of MnO 2 with KOH in presence of O 2 produces a salt W. Alkaline solution of W upon electrolytic oxidation yields another salt X. The manganese containing ions present in W and X, respectively, are Y and Z. Correct statement(s) is(are)
A
In aqueous acidic solution, Y undergoes disproportionation reaction to give Z and MnO 2
B
In both Y and Z, 
-bonding occurs between p-orbitals of oxygen and d-orbitals of manganese
-bonding occurs between p-orbitals of oxygen and d-orbitals of manganese
C
Y is diamagnetic in nature while Z is paramagnetic
D
Both Y and Z are coloured and have tetrahedral shape
Text Solution
