Select the correct answer.

Which compound is inorganic?

A. [tex]C _6 H _{12} O _6[/tex]
B. [tex]KH _2 PO _4[/tex]
C. [tex]CH _3 COOH[/tex]
D. [tex]C _2 H _6[/tex]
E. [tex]C _2 H _5 OH[/tex]



Answer :

To determine which compound is inorganic, we need to understand the difference between organic and inorganic compounds. Organic compounds primarily consist of carbon atoms bonded with hydrogen, and possibly with oxygen, nitrogen, phosphorus, sulfur, and other elements. In contrast, inorganic compounds do not follow this specific carbon-hydrogen structure and usually include metals and other elements.

Let's analyze each option:

A. [tex]\(C_6H_{12}O_6\)[/tex]: This is glucose, a well-known sugar that is an organic compound. It contains carbon, hydrogen, and oxygen atoms.

B. [tex]\(KH_2PO_4\)[/tex]: This is potassium dihydrogen phosphate, a salt composed of potassium (K), hydrogen (H), phosphorus (P), and oxygen (O). This compound does not follow the typical organic structure and is considered inorganic.

C. [tex]\(CH_3COOH\)[/tex]: This is acetic acid, an organic compound that contains carbon atoms bonded with hydrogen and oxygen.

D. [tex]\(C_2H_6\)[/tex]: This is ethane, an organic compound comprising only carbon and hydrogen atoms in a typical organic structure.

E. [tex]\(C_2H_5OH\)[/tex]: This is ethanol (alcohol), an organic compound containing carbon, hydrogen, and oxygen in an organic structure.

From the analysis, the only inorganic compound in the list is:

B. [tex]\(KH_2PO_4\)[/tex]

Thus, the correct answer is:

B. [tex]\(KH_2PO_4\)[/tex]
