14. Which of the following is not an organic compound?

Answer: A

Explanation:

H₂O is not an organic compound.

H₂O, commonly known as water, does not contain carbon and is therefore classified as an inorganic compound.

A) H₂O

This option is correct as H₂O, or water, lacks carbon in its molecular structure, which is a fundamental criterion for classifying a compound as organic. Organic compounds are primarily characterized by the presence of carbon atoms bonded to hydrogen and other elements.

B) C₂H₆

C₂H₆ represents a hydrocarbon, which is an organic compound made up of carbon and hydrogen. This structure meets the definition of organic compounds, thereby making this option incorrect.

C) C₃H₇O₂

C₃H₇O₂ is another example of an organic compound, specifically a fatty acid, which contains carbon, hydrogen, and oxygen. As it contains carbon atoms, this option does not fit the criteria for being classified as an inorganic compound.

D) None of the above

This option implies that all provided choices are organic compounds. Since H₂O is indeed inorganic, this option is incorrect as it contradicts the classification of H₂O.

Conclusion

H₂O is definitively the only option that does not qualify as an organic compound due to its lack of carbon. All other options provided contain carbon and therefore are classified as organic. This distinction underscores the fundamental difference between organic and inorganic compounds.
