Which of the following graph(s) will correspond to a SN1 reaction mechanism?
Open in App
Solution
The correct option is C
SN1 mechanism involves two steps
(i) Formation of carbocation
(ii) Attack of nucleophile
Here, the formation of carbocation is the slow and rate determining step.
Thus, the rate of the reaction depends only on the reactant.
Since, nucleophile does not involve in rate determining step, it does not determine the rate of the reaction.
Rate of reaction=[R−X]1[Nu]0
Thus, graphs (b) and (c) are corresponds to the SN1 reaction.
