Which one is an organic compound_____________?
Correct answer: C. Lipids
- A. CO2
- B. Water
- C. Lipids
- D. HCI
Explanation
Lipids are organic compounds because they contain carbon-based structures and are produced by living organisms. CO2 contains carbon but is classified as an inorganic compound because it lacks the complex carbon-hydrogen framework typical of organic molecules. Students most likely choose CO2 by assuming every carbon-containing compound is organic.
