To classify each item as organic (O) or inorganic (I), we need to look at their chemical structures and determine whether they contain carbon-hydrogen (C-H) bonds. Organic compounds typically contain these bonds, while inorganic compounds generally do not. Let's classify each one step-by-step:
1. Table salt (NaCl)
- Table salt consists of sodium (Na) and chlorine (Cl).
- It does not contain any carbon-hydrogen (C-H) bonds.
- Therefore, table salt is classified as inorganic (I).
2. TNT (C7H5N3O9)
- TNT (trinitrotoluene) has a chemical structure that includes carbon (C) and hydrogen (H) bonds.
- Since TNT contains C-H bonds, it is classified as organic (O).
3. Glucose (C6H12O6)
- Glucose is a well-known example of a simple sugar and has a chemical formula that includes carbon (C) and hydrogen (H) bonds.
- Thus, glucose is organic (O).
4. 2, 4-D (C3H6O3Cl2)
- 2, 4-D is a type of herbicide and has a chemical structure that includes carbon (C) and hydrogen (H) bonds.
- Therefore, 2, 4-D is classified as organic (O).
5. Limestone (CaCO3)
- Limestone is primarily composed of calcium carbonate (CaCO3).
- There are no carbon-hydrogen (C-H) bonds in limestone.
- Hence, limestone is inorganic (I).
6. Water (H2O)
- Water consists of hydrogen (H) and oxygen (O) but no carbon.
- Since water does not contain any carbon-hydrogen (C-H) bonds, it is classified as inorganic (I).
So, the classifications are:
- Table salt (NaCl) [tex]$\square$[/tex] I
- TNT (C7H5N3O9) [tex]$\square$[/tex] O
- Glucose (C6H12O6) [tex]$\square$[/tex] O
- 2, 4-D (C3H6O3Cl2) [tex]$\square$[/tex] O
- Limestone (CaCO3) [tex]$\square$[/tex] I
- Water (H2O) [tex]$\square$[/tex] I
