Which of the following organic halogen compound has high reactivity towards \(S_N1\) mechanism?
Show Hint
$S_{N}1$ Reactivity: Tertiary $>$ Secondary $>$ Primary.
Updated On: Apr 27, 2026
- Chloroethane
- Iodoethane
- Chlorobenzene
- 2-Chloropropane
- Benzyl chloride
Show Solution
Verified By Collegedunia
The Correct Option is
Solution and Explanation
Step 1: Concept
$S_{N}1$ reactivity depends on the stability of the carbocation intermediate.
Step 2: Meaning
Benzyl carbocation is highly stable due to resonance with the benzene ring.
Step 3: Analysis
Primary and secondary alkyl halides are less reactive than benzylic halides in $S_{N}1$ conditions.
Step 4: Conclusion
Hence, the correct answer is Benzyl chloride.
Final Answer: (E)
