Q. The reaction, $P_{4} + 3NaOH + 3H_{2}O \longrightarrow 3{NaH}_{2}{PO}_{2} + {PH}_{3}$ is an example of
A) Disproportionation reaction
B) Neutralisation reaction
C) Double-decomposition reaction
D) Pyrolytic reaction
Explanation
(a)
Reduction (oxidation number decreases)
[image:8_image14.emf]
Oxidation (oxidation number is increases)
The reactions in which the same substance undergoes oxidation as well as reduction, are called disproportionation reactions.
So, the above reaction is an example of disproportionation reaction.
