An incorrect statement with respect to \( S_{N} 1 \) and \( S_{N} 2 \) mechanisms for alkyl halide is
- oxamsnet copp
- A Competing reaction for an \( S_{N} 2 \) reaction is rearrangement.
- B A weak nucleophile and a protic solvent increases the rate or favours \( S_{N} 1 \) reaction.
- C A strong nucleophile in an aprotic solvent increases the rate or favours \( S_{N} 2 \) reaction.
- D \( S_{N} 1 \) reactions can be catalyzed by some Lewis acids.
Answer & Solution
Correct Answer
(A) Competing reaction for an \( S_{N} 2 \) reaction is rearrangement.
Step-by-step Solution
Detailed explanation
Competing reaction for an SN2 reaction is elimination not rearrangement. Because, substitution and elimination real
often complete with each other. Most bases are also nucleophiles and can engage in substitution or elimination
depending upon the alkyl halide and the reaction conditions.
