To determine which compound among the given options is inorganic, we need to understand the distinguishing features between organic and inorganic compounds.
Organic compounds are generally defined as compounds that contain carbon atoms bonded to hydrogen atoms. Most organic compounds will have carbon-hydrogen (C-H) bonds. Let's analyze each option:
A. [tex]\( C_6H_{12}O_6 \)[/tex]
This is glucose, which is a simple sugar. It contains carbon, hydrogen, and oxygen atoms, and it has multiple C-H bonds. Hence, it is an organic compound.
B. [tex]\( KH_2PO_4 \)[/tex]
This is potassium dihydrogen phosphate, which contains potassium (K), hydrogen (H), phosphorus (P), and oxygen (O). There are no C-H bonds here, making it an inorganic compound.
C. [tex]\( CH_3COOH \)[/tex]
This is acetic acid, which consists of carbon, hydrogen, and oxygen atoms. It possesses C-H bonds, categorizing it as an organic compound.
D. [tex]\( C_2H_6 \)[/tex]
This is ethane, composed solely of carbon and hydrogen atoms with C-H bonds, classifying it as an organic compound.
E. [tex]\( C_2H_5OH \)[/tex]
This is ethanol, containing carbon, hydrogen, and oxygen atoms. It also has C-H bonds, so it is an organic compound.
After examining each choice:
- [tex]\( C_6H_{12}O_6 \)[/tex] (A) is organic.
- [tex]\( KH_2PO_4 \)[/tex] (B) is inorganic.
- [tex]\( CH_3COOH \)[/tex] (C) is organic.
- [tex]\( C_2H_6 \)[/tex] (D) is organic.
- [tex]\( C_2H_5OH \)[/tex] (E) is organic.
Therefore, the correct answer is:
B. [tex]\( KH_2PO_4 \)[/tex]
