Vedclass · Answer

(B) Ethanol can be converted to iodoethane by first converting it into a better leaving group,such as a chloroalkane,and then performing a nucleophilic substitution reaction (Finkelstein reaction) using $NaI$ in acetone.Step $1$: $C_{2}H_{5}OH + HCl \xrightarrow{ZnCl_{2}} C_{2}H_{5}Cl + H_{2}O$Step $2$: $C_{2}H_{5}Cl + NaI \xrightarrow{	ext{Acetone}} C_{2}H_{5}I + NaCl$

How can you obtain iodoethane from ethanol when no other iodine containing reagent except $NaI$ is available in the laboratory?
