Question

which example is most likely an inorganic compound?
○ methane, which is made of carbon and hydrogen
○ glucose, which is a sugar made by plants
○ sodium chloride, which is a salt
○ human dna, which is a molecule in cells

Explanation:

Inorganic compounds are typically not based on carbon - hydrogen (C - H) bonds (except for some exceptions like carbonates, cyanides, etc.). Methane ($CH_4$) has C - H bonds and is organic. Glucose ($C_6H_{12}O_6$) is a carbohydrate with C - H bonds and is organic. Human DNA is a complex organic molecule with carbon - based structures. Sodium chloride (NaCl) is a salt composed of sodium and chloride ions, and it does not have C - H bonds, so it is an inorganic compound.

Answer:

C. sodium chloride, which is a salt
