Single DisplacementSingle Displacement
A chemical reaction whereby a free element A chemical reaction whereby a free element substitutes for another element in a compound.substitutes for another element in a compound.
In this type of reaction, displacement normally In this type of reaction, displacement normally occurs when A is more reactive than Boccurs when A is more reactive than B
