Which one is more stable in SN1 reaction: benzyl or methyl?
Understand the Problem
The question is asking to compare the stability of benzyl and methyl groups in the context of SN1 reactions. This involves understanding how the structure of these groups affects their stability as carbocations, which is crucial for the mechanism of SN1 reactions.
Answer
Benzyl is more stable in an SN1 reaction than methyl.
Benzyl is more stable in an SN1 reaction compared to methyl.
Answer for screen readers
Benzyl is more stable in an SN1 reaction compared to methyl.
More Information
Benzyl's stability in SN1 reactions is due to resonance stabilization. The positive charge on the carbocation can be delocalized over the aromatic ring, which enhances stability, whereas methyl lacks this stabilization.
Tips
A common mistake is not considering the role of resonance in stabilizing carbocations, which is crucial in understanding the difference in reactivity.
