The compound classified as a hydrocarbon is:
A. ethane
Explanation:
1. Hydrocarbons are organic compounds made up of only hydrogen and carbon atoms.
2. Ethane (C2H6) is a hydrocarbon because it consists of hydrogen and carbon atoms only, with no other elements present.
3. In contrast, ethanol (B) contains oxygen in addition to hydrogen and carbon, making it not a hydrocarbon.
4. Chloroethane (C) contains chlorine in addition to hydrogen and carbon, so it is not a hydrocarbon.
5. Ethanoic acid (D) contains oxygen in the form of a carboxyl group, so it is not a hydrocarbon.
Therefore, the correct answer is ethane (A) as it is the compound classified as a hydrocarbon in the given options.
