검증된 단계별 안내1
Identify the starting material: C\_2H\_5Br is bromoethane, an alkyl halide where a bromine atom is attached to an ethyl group.
Recognize the reagent and conditions: aqueous KOH under reflux typically promotes nucleophilic substitution reactions, where the hydroxide ion (OH\^-) acts as a nucleophile.
Determine the type of reaction: since the solvent is aqueous and the conditions are reflux, the reaction proceeds mainly via an SN2 mechanism, where OH\^- replaces Br in bromoethane.
Write the substitution reaction: C\_2H\_5Br + OH\^- \(\rightarrow\) C\_2H\_5OH + Br\^- , where the bromine atom is replaced by a hydroxyl group, forming an alcohol.
Name the product using IUPAC rules: the product is an ethyl group attached to a hydroxyl group, which is named ethanol.
