Solution

The correct option is C Molecularity is $2$ but order of reaction is $1$
As water used is in large excess thus, 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 $2$ .

In the hydrolysis of organic chloride in the presence of a large excess of water,RCl+H2O→ROH+HCl

The correct option is C Molecularity is 2 but order of reaction is 1As water used is in large excess thus, 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.
