Vedclass · Answer

(A) $S_N1$ reaction characteristics are as follows:$(1)$ Rearrangement is possible because a carbocation intermediate is formed.$(2)$ The rate is affected by the polarity of the solvent as it stabilizes the carbocation intermediate.$(3)$ The strength of the nucleophile is $NOT$ important in determining the rate,as the rate-determining step involves only the substrate.$(4)$ The reactivity series is tertiary $>$ secondary $>$ primary due to the stability of the carbocation formed.$(5)$ It proceeds with racemization (not complete inversion) because the nucleophile can attack from either side of the planar carbocation.Therefore,statements $(3)$ and $(5)$ are not correctly associated with the $S_N1$ reaction.
