To determine which compound is inorganic, we need to understand the distinction between organic and inorganic compounds.
Organic compounds typically contain carbon atoms bonded to hydrogen atoms and often include other elements such as oxygen, nitrogen, sulfur, or halogens. Inorganic compounds, on the other hand, may contain carbon but do not include carbon-hydrogen bonds, and they often include minerals, metals, salts, and substances derived from minerals.
Let's analyze each given compound:
A. [tex]\(C_6H_{12}O_6\)[/tex] (Glucose):
- This is a carbohydrate, which is an organic compound because it contains carbon-hydrogen bonds.
B. [tex]\(KH_2PO_4\)[/tex] (Potassium Dihydrogen Phosphate):
- This is a salt and does not contain carbon-hydrogen bonds. It is classified as an inorganic compound.
C. [tex]\(CH_3COOH\)[/tex] (Acetic Acid):
- This compound is an organic acid because it contains carbon-hydrogen bonds.
D. [tex]\(C_2H_6\)[/tex] (Ethane):
- This is a hydrocarbon, and it contains carbon-hydrogen bonds, making it an organic compound.
E. [tex]\(C_2H_5OH\)[/tex] (Ethanol):
- This is an alcohol, and it contains carbon-hydrogen bonds, classifying it as an organic compound.
From this analysis, we conclude that the inorganic compound among the options is:
B. [tex]\(KH_2PO_4\)[/tex]
Therefore, the correct answer is:
2
