The compound that does not undergo hydrolysis by \(S_N1\) mechanism is
The compound that does not undergo hydrolysis by \(S_N1\) mechanism is
Show Hint
Aryl halides do not undergo \(S_N1\) easily because phenyl carbocation is unstable.

- \(C_6H_5CH_2Cl\)
- \(C_6H_5CH(CH_3)Cl\)
- \(C_6H_5Cl\)
- \(CH_3CH_2Cl\)
- \(C_6H_5CH(C_6H_5)Cl\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Aryl halides like chlorobenzene do not undergo \(S_N1\) easily because formation of phenyl carbocation is highly unstable.
Step 1: Identify aryl halide.
\[ C_6H_5Cl \] is chlorobenzene.
Step 2: Reason for no \(S_N1\).
For \(S_N1\), carbocation formation is required. Phenyl carbocation is unstable and not formed easily.
Step 3: Conclusion.
Thus, chlorobenzene does not undergo hydrolysis by \(S_N1\) mechanism.
