Which of the compounds will react faster in SN1reaction with the OH ion? CH3−CH2−Cl or C6H5−CH2−Cl

This is a short answer type question as classified in NCERT Exemplar In an SN1 reaction with the OH ion, C6H5−CH2−Cl will react quicker. This is owing to the carbocation's stability in the compound. The C6H5 group is already stable owing to resonance, and the CH2 attached will receive that stability after the cleavage in the first stage of the SN1 reaction, resulting in a stable C6H5CH2+ carbocation. CH3-CH2-Cl does not have the same sort of carbocation.
