Q4. Alkyl halides are good at doing substitution (SN2/SN1) and elimination (E1/E2) reactions because the halide (X-) is a good LG. Alcohols on the other hand are not suitable for these reactions since hydroxide (¯OH) is a poor LG. However, an OH can be converted into a OTs (tosyl group) by reacting an alcohol with TsCl in presence of a base. An OTs is a good LG, and this allows us to indirectly (via OTs) use alcohols in substitution (SN2/SN1) and elimination (E1/E2) reactions.
