The compound which undergoes SN1 reaction most rapidly is:
Show Hint
The Correct Option is A
Solution and Explanation
In SN1 reactions, the rate-determining step is the departure of the leaving group. In the case of aromatic compounds, a resonance-stabilized carbocation can form if the leaving group is attached to the ring, which makes the reaction faster. Hence, the phenyl bromide (C6H5Br) undergoes the reaction most rapidly.
