In S N 1 reactions step 1 is slow and reversible, and the slowest step is the rate determining step.

(i), (iii) and (iv) are correct

(ii), (iii) and (iv) are correct

only (iii) and (iv) are correct

(i), (ii) and (iv) are correct

In SN​1 reactions step 1 is slow and reversible, and the slowest step is the rate determining step.

In $S_{N} 1$ reactions step $1$ is slow and reversible, and the slowest step is the rate determining step.
