Introduction:
Organic compounds are generally defined as compounds that contain carbon atoms bonded to hydrogen atoms. However, not all carbon-containing compounds are considered organic. Carbon dioxide (CO2), carbon monoxide (CO), and other carbonic compounds do not fall under the category of organic compounds due to the following reasons:

Lack of Carbon-Hydrogen (C-H) bonds:
One of the fundamental characteristics of organic compounds is the presence of covalent bonds between carbon and hydrogen atoms. These bonds are responsible for the unique properties of organic compounds, such as hydrophobicity and combustion. However, carbon dioxide, carbon monoxide, and carbonic compounds do not have carbon-hydrogen bonds. Instead, they have carbon-oxygen (C-O) bonds, which are characteristic of inorganic compounds.

Chemical Stability and Reactivity:
Organic compounds typically exhibit a wide range of chemical reactivity due to the presence of carbon-hydrogen bonds. Carbon dioxide, carbon monoxide, and carbonic compounds, on the other hand, are relatively stable and do not readily participate in organic chemical reactions. They are less reactive compared to organic compounds, which limits their classification as organic.

Carbonic Acid and Carbonate Salts:
Carbon dioxide can react with water to form carbonic acid (H2CO3), which can further dissociate into bicarbonate (HCO3-) and carbonate (CO32-) ions. These compounds are considered inorganic due to their chemical properties and behavior. They are commonly found in inorganic chemistry and are distinct from organic compounds.

Classification as Inorganic Compounds:
Based on the chemical properties, structures, and reactions, carbon dioxide, carbon monoxide, and carbonic compounds are more accurately classified as inorganic compounds. Inorganic chemistry focuses on the study of compounds that do not contain carbon-hydrogen bonds, including minerals, acids, and salts.

Conclusion:
In summary, carbon dioxide, carbon monoxide, and carbonic compounds are not considered organic compounds because they lack carbon-hydrogen bonds, exhibit different reactivity patterns, form inorganic carbonates and bicarbonates, and are more appropriately classified as inorganic compounds. It is important to understand the distinction between organic and inorganic compounds to accurately categorize and study different types of carbon-containing substances.
