Final answer:
In the field of chemistry, sulfuric acid and ammonia are classified as inorganic, while methane, aspirin, rubbing alcohol, and Novocaine are classified as organic compounds.
Step-by-step explanation:
The classification of substances into organic or inorganic chemistry can be determined by analyzing whether they are primarily carbon-based compounds, which are typical of organic chemistry, or not.
- Sulfuric acid (H₂SO₄) is an inorganic compound as it does not primarily consist of carbon and hydrogen.
- Methane (CH₄) is an organic compound as it is composed of carbon and hydrogen atoms.
- Ammonia (NH₃) is an inorganic compound; despite containing hydrogen, it lacks a carbon-based structure.
- Aspirin (C₉H₈O₄) is an organic compound, with a structure primarily made up of carbon, hydrogen, and oxygen.
- Rubbing alcohol (C₃H₇OH, also known as isopropyl alcohol) is organic due to its carbon and hydrogen content.
- Novocaine (C₁₃H₂₂N₂O₂) is also an organic compound, as it contains a complex carbon-based structure.
