HALOALKANES AND HALOARENES

90884 An incorrect statement with respect to $S_{N} 1$ and $\mathrm{S}_{\mathrm{N}} 2$ mechanism for alkyl halide is-

1 a strong nucleophile is an aprotic solvent increases the rate or favours $\mathrm{S}_{\mathrm{N}} 2$ reaction.
2 Competing reaction for $\mathrm{S}_{\mathrm{N}} 2$ reaction is rearrangement
3 $\mathrm{S}_{\mathrm{N}} 1$ reactions can be catalysed by some Lewis acids
4 a weak nucleophile and a protic solvent increases the rate of $S_{N} 1$ reaction
