Answer & explanation
Correct answer: option 3
The correct answer is option 3. n-propyl bromide.
To prepare a pure sample of n-hexane using sodium metal as one reactant, the other reactants will be n-propyl bromide. This reaction is known as the Wurtz reaction. It involves treating two molecules of an alkyl halide (like n-propyl bromide, \(CH_3CH_2CH_2Br\)) with sodium metal in a dry ether solvent. The reaction proceeds as follows:
