To determine which compound is inorganic, we need to understand the difference between organic and inorganic compounds.
Organic compounds are generally composed of carbon atoms in combination with hydrogen, oxygen, nitrogen, and other elements. They typically contain C-H (carbon-hydrogen) bonds.
Inorganic compounds are typically not based on carbon-hydrogen combinations. They may contain carbon, but if they do, it is not in the form of C-H bonds commonly found in organic compounds.
Now, let's look at each option:
A. [tex]\( C_6H_{12}O_6 \)[/tex] (Glucose) \
This is an organic compound as it contains carbon atoms bonded with hydrogen and oxygen atoms.
B. [tex]\( KH_2PO_4 \)[/tex] (Potassium Dihydrogen Phosphate) \
This is an inorganic compound. It does not contain any carbon-hydrogen (C-H) bonds. Instead, it is composed of potassium (K), hydrogen (H), phosphorus (P), and oxygen (O).
C. [tex]\( CH_3COOH \)[/tex] (Acetic Acid) \
This is an organic compound as it contains carbon atoms in C-H bonds and also bonded with oxygen atoms.
D. [tex]\( C_2H_6 \)[/tex] (Ethane) \
This is an organic compound as it contains carbon atoms bonded with hydrogen atoms (C-H bonds).
E. [tex]\( C_2H_5OH \)[/tex] (Ethanol) \
This is an organic compound as it contains carbon atoms bonded with hydrogen atoms (C-H bonds) and oxygen.
Therefore, the correct answer, the compound that is inorganic, is:
B. [tex]\( KH_2PO_4 \)[/tex]
