Question

Which of the following is not a
disproportionation reaction
A
P4 + 3NaOH + 3H2O
+ PH3 + NaH2PO2
B.
Cl2 + NaOH + NaCIO
+ NaCl + H2O
C
Mg + 2HCl MgCl2
+ H2
D
4KCIO3 + 3KCIO4
+ + KCI​

Answer 1

Answer:

P4+3NaOH+3H2O→PH3+3NaH2PO2

In reactant P is present in (0) oxidation state and in PH3, it is present in (−3) oxidation state and in NaH2PO2 it is present in (+1) oxidation state.

P undergoes both oxidation and reduction. So this is an example of disproportionation reaction

Answer 2

Answer:

options P4 + 3NaOH + 3H20 + PH3 + NaH2POW
