The correct statement regarding the mechanism involved in the above reactions is
Show Hint
In SN1, bond cleavage is rate-determining; in aryl systems with EWGs, the reaction can proceed faster.
Updated On: Jun 3, 2025
- In both I, II C--Cl bond is cleaved in slow step of the reaction
- In both I, II C--Cl bond is cleaved in fast step of the reaction
- In I C--Cl bond is cleaved in slow step and in II fast step of the reaction
- In I C--Cl bond is cleaved in fast step and in II slow step of the reaction
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In the SN1 mechanism (reaction I), the C--Cl bond breaks in the slow step, forming a carbocation. In reaction II (aromatic nucleophilic substitution), the presence of strong electron-withdrawing groups facilitates faster bond cleavage.
