Final answer:
The most likely inorganic compound among the options is carbon dioxide (CO2). Organic compounds contain both carbon and hydrogen, while inorganic compounds do not include both elements, qualifying CO2 as inorganic.
Step-by-step explanation:
The compound that is most likely inorganic among the options given is carbon dioxide (CO2). Organic compounds are usually composed of both carbon (C) and hydrogen (H) atoms and are synthesized by living organisms. Examples of organic compounds include methane (CH4), glucose (C6H12O6), and many others that contain C-H bonds. Inorganic compounds may contain hydrogen or carbon but generally not both together, except for a few exceptions like carbonates and oxides, which include carbon dioxide. Since carbon dioxide consists solely of carbon and oxygen without hydrogen, it is classified as an inorganic compound.
