Vedclass · Answer

(C) $S_{N}1$ reactions proceed via the formation of a carbocation intermediate. The rate of the reaction depends only on the concentration of the substrate,not on the concentration of the nucleophile. $3^{\circ}$-alkyl halides are most reactive towards $S_{N}1$ due to the stability of the resulting carbocation. $1^{\circ}$-alkyl halides generally undergo $S_{N}2$ reactions because they form unstable carbocations. Polar solvents stabilize the transition state and the carbocation intermediate,thus favouring $S_{N}1$ reactions. Therefore,the statement that $1^{\circ}$-alkyl halides generally react through $S_{N}1$ reaction is incorrect.
