    In the hydrolysis of an organic chloride in presence of large excess of water, \[RCl+{{H}_{2}}O\to ROH+HCl\]

    A)  molecularity and order of reaction both are 2

    B)  molecularity is 2 but order of reaction is 1

    C)  molecularity is 1 but order of reaction is 2

    D)  molecularity is 1 and order of reaction is also 1

    Correct Answer: B

    Solution :

                     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.
