Questions: The reaction of ethane (C2H6) with bromine gas (Br2) could yield which of the following products? None of the above C2H5Br C2H3Br3 HBr All of the above

Solution Steps

The reaction in question involves ethane (\(\mathrm{C}_{2} \mathrm{H}_{6}\)) and bromine gas (\(\mathrm{Br}_{2}\)). This is a typical halogenation reaction where a hydrogen atom in ethane is replaced by a bromine atom, resulting in the formation of a bromoalkane and hydrogen bromide (HBr).

1. \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}\): This is ethyl bromide, a common product of the bromination of ethane.
2. \(\mathrm{C}_{2} \mathrm{H}_{3} \mathrm{Br}_{3}\): This compound is unlikely to form directly from the reaction of ethane with bromine, as it suggests multiple bromination steps and a different structure.
3. HBr: Hydrogen bromide is a byproduct of the bromination reaction.

• None of the above: This is incorrect because \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}\) and HBr are valid products.
• All of the above: This is incorrect because \(\mathrm{C}_{2} \mathrm{H}_{3} \mathrm{Br}_{3}\) is not a direct product of the reaction.
