How do polar solvents help in the first step in $S_{N}1$ mechanism?
(N/A) Polar solvents possess a high dielectric constant,which facilitates the ionization of the $C-X$ bond in alkyl halides to form a carbocation intermediate.
Specifically,the role of the polar solvent is:
$(i)$ To stabilize the transition state and promote the ionization of the alkyl halide to form a carbocation.
$(ii)$ To solvate the resulting ions (carbocation and halide ion) through ion-dipole interactions,thereby preventing their recombination.
