Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

${\mathrm{I}}^{-}$is a good nucleophile as well as a good leaving group. Therefore, if $(R)$-2-iodobutane is treated with $\mathrm{NaI}$, repeated ${\mathrm{S}}_{\mathrm{N}}2$ reactions occur. As a result, eventually a racemic mixture of $(\pm )$-2-iodobutane is obtained.
