In the hydrolysis of an organic chloride in presence of large excess of water,
Molecularity and order of reaction both are 2
Molecularity is 1 but order of reaction is 2
Molecularity is 2 but order of reaction is 1
Molecularity and order of reaction both are 1
As water used is in large excess thus, the order depends only upon the concentration of RCl.
However molecularity is the number of reactants taking part in a reaction, thus, here is equal to 2.
