Consider the following reactions I, II and III. The correct order of reactivity of X, Y and Z towards $S_{N}1$ reaction is:
Show Hint
Stable carbocation = Faster $S_{N}1$ reaction.
Updated On: Jun 3, 2026
- $Z > Y > X$
- $X > Z > Y$
- $X > Y > Z$
- $Z > X > Y$
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
$S_{N}1$ reactivity depends primarily on the stability of the carbocation intermediate formed during the rate-determining step.
Step 2: Meaning
Carbocation stability generally follows the order: tertiary $>$ secondary $>$ primary.
Step 3: Analysis
Reaction conditions that favor the formation of more substituted or resonance-stabilized carbocations will increase reactivity in $S_{N}1$ processes.
Step 4: Conclusion
Based on the comparative structural analysis of substrates X, Y, and Z, the reactivity order is $Z > Y > X$.
Final Answer: (A)
