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 among the given options, let's analyze each compound and see whether it contains a carbon atom. Generally, compounds that contain carbon atoms are classified as organic compounds, while those without carbon atoms are classified as inorganic compounds.

A. [tex]\(C _6 H _{12} O _6\)[/tex]

This compound is glucose, which is a carbohydrate. It has carbon atoms in its structure, making it an organic compound.

B. [tex]\(KH _2 PO _4\)[/tex]

This compound is potassium dihydrogen phosphate. It does not contain any carbon atoms, classifying it as an inorganic compound.

C. [tex]\(CH _3 COOH\)[/tex]

This compound is acetic acid, which is an organic acid. It contains carbon atoms, making it an organic compound.

D. [tex]\(C _2 H _6\)[/tex]

This compound is ethane, which is a hydrocarbon. It has carbon atoms in its structure, making it an organic compound.

E. [tex]\(C _2 H _5 OH\)[/tex]

This compound is ethanol, which is an alcohol. It contains carbon atoms, making it an organic compound.

After analyzing all options, we find that:
- A. [tex]\(C _6 H _{12} O _6\)[/tex] is organic.
- B. [tex]\(KH _2 PO _4\)[/tex] is inorganic.
- C. [tex]\(CH _3 COOH\)[/tex] is organic.
- D. [tex]\(C _2 H _6\)[/tex] is organic.
- E. [tex]\(C _2 H _5 OH\)[/tex] is organic.

Therefore, the correct answer is:

B. [tex]\(KH _2 PO _4\)[/tex]
