Question

An incorrect statement with respect to $ S_{N} 1 $ and $ S_{N} 2 $ mechanisms for alkyl halide is - oxamsnet copp, Competing reaction for an $ S_{N} 2 $ reaction is rearrangement., A weak nucleophile and a protic solvent increases the rate or favours $ S_{N} 1 $ reaction., A strong nucleophile in an aprotic solvent increases the rate or favours $ S_{N} 2 $ reaction., $ S_{N} 1 $ reactions can be catalyzed by some Lewis acids.

MARKS App · Accepted Answer

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.
