CUET Preparation Today
To prepare a pure sample of n-hexane using sodium metal as one reactant, the other reactants will be |
ethyl chloride and n-butyl chloride methyl bromide and n-pentyl bromide n-propyl bromide ethyl bromide and n-butyl bromide |
n-propyl bromide |
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:
