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 analyze each of the given options. Inorganic compounds are typically those which do not contain carbon-hydrogen (C-H) bonds, although there are exceptions. Organic compounds generally contain carbon atoms bonded to hydrogen atoms, and often other elements such as oxygen and nitrogen.

Let's examine each option:

A. [tex]\(C_6H_{12}O_6\)[/tex]
- This is glucose, a well-known organic compound because it contains carbon-hydrogen bonds.

B. [tex]\(KH_2PO_4\)[/tex]
- This is potassium dihydrogen phosphate, which is classified as an inorganic compound because it does not contain carbon-hydrogen bonds and consists of potassium, hydrogen, phosphorus, and oxygen.

C. [tex]\(CH_3COOH\)[/tex]
- This is acetic acid, an organic compound as it contains carbon-hydrogen bonds.

D. [tex]\(C_2H_6\)[/tex]
- This is ethane, an organic compound consisting entirely of carbon and hydrogen.

E. [tex]\(C_2H_5OH\)[/tex]
- This is ethanol, another organic compound that contains carbon-hydrogen bonds.

From the given options:

- Option A is glucose, an organic compound.
- Option B is potassium dihydrogen phosphate, which is inorganic.
- Option C is acetic acid, an organic compound.
- Option D is ethane, an organic compound.
- Option E is ethanol, an organic compound.

Therefore, the correct answer is:

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

The compound [tex]\(KH_2PO_4\)[/tex] is inorganic.
