Which of the following compounds is NOT an organic compound? CH3OH C4H10 NO2 C6H12O6 C8H18
The Correct Answer and Explanation is:
Correct Answer: NO₂
Explanation:
Organic compounds are defined as chemical compounds that primarily contain carbon atoms bonded to hydrogen, often along with oxygen, nitrogen, sulfur, or other nonmetals. They are typically associated with living organisms or are synthesized from carbon-based structures. Common examples include hydrocarbons, alcohols, acids, and sugars.
Let us analyze each of the given compounds:
- CH₃OH (Methanol): This compound contains a carbon atom bonded to three hydrogen atoms and one hydroxyl group (OH). It is a simple alcohol and clearly organic.
- C₄H₁₀ (Butane): This is a hydrocarbon consisting only of carbon and hydrogen atoms. It is classified as an alkane, a common type of organic molecule.
- NO₂ (Nitrogen dioxide): This compound does not contain any carbon atoms. It consists only of nitrogen and oxygen. Since organic chemistry revolves around carbon-based molecules, NO₂ is not considered an organic compound. It is classified as an inorganic compound and is typically found as a pollutant in the atmosphere.
- C₆H₁₂O₆ (Glucose): This is a sugar with a carbon backbone, multiple hydroxyl groups, and a carbonyl group. It is a classic example of an organic compound involved in biological energy processes.
- C₈H₁₈ (Octane): This is another hydrocarbon, specifically an alkane, containing eight carbon atoms and eighteen hydrogen atoms. It is also an organic compound, often found in gasoline.
In summary, while most of the listed compounds have a carbon backbone and qualify as organic, NO₂ lacks carbon altogether. Therefore, NO₂ is not an organic compound, making it the correct answer. It belongs to the category of inorganic compounds.
