To determine which of the given compounds is an organic molecule, we need to understand the definition of organic molecules. Organic molecules are typically characterized by the presence of carbon atoms bonded to hydrogen atoms. Let's examine each option in detail:
A. [tex]\( \text{NaCl} \)[/tex]
- This is sodium chloride, a compound made up of sodium (Na) and chlorine (Cl). There is no carbon atom present in this compound.
B. [tex]\( \text{FeO} \)[/tex]
- This is iron(II) oxide, consisting of iron (Fe) and oxygen (O). Again, there is no carbon atom present in this compound.
C. [tex]\( \text{H}_2\text{O} \)[/tex]
- This is water, made up of hydrogen (H) and oxygen (O). There is no carbon atom in this molecule.
D. [tex]\( \text{CH}_4 \)[/tex]
- This is methane, a compound consisting of one carbon (C) atom bonded to four hydrogen (H) atoms. This compound contains carbon-hydrogen (C-H) bonds, which is a characteristic feature of organic molecules.
Since organic molecules contain carbon-hydrogen bonds, the correct answer is:
D. [tex]\( \text{CH}_4 \)[/tex]
Therefore, the organic molecule among the given options is [tex]\( \text{CH}_4 \)[/tex] (Methane).
