1.	How do polar solvents help in the first step in S_(N)1 mechanism ?
Answer» SOLUTION :The `S_(N)1` mechanism proceeds through the formation of carbocation. It involves breaking of C-halogen bond for which energy is obtained through the solvation of HALIDE ION with the proton of the protic solvent. Thus, polar solvents help in ionisation step by stabilizing the IONS by solvation.
