The molecularity of a reaction refers to the number of molecules or atomic species involved in the reaction's rate-determining step. In the given reaction, CH3NC ---> CH3CN, there is only one molecule involved in the reaction and it undergoes a change. Therefore, the molecularity of this elementary reaction is "one" or "uni-molecular".
To determine the molecularity of an elementary reaction, you need to consider the number of reactant molecules involved in the reaction. The molecularity describes how many species are involved in a single elementary step of a reaction.
In the given reaction, CH3NC ---> CH3CN, there is only one reactant molecule (CH3NC). Therefore, the molecularity of this reaction is "one" or "unimolecular".
So, the correct answer is "one".
