As a specialist in the field of chemistry, I can provide you with an in-depth explanation of why carbon dioxide is considered inorganic. The distinction between organic and inorganic compounds is based on a set of traditional definitions that have evolved over time in the field of chemistry.

Organic compounds are traditionally defined as compounds that contain carbon atoms bonded to hydrogen atoms, often referred to as hydrocarbons. This definition is rooted in the historical context of organic chemistry, which initially focused on compounds derived from living organisms. However, the modern understanding of organic chemistry has expanded to include a vast array of carbon-containing compounds that are not necessarily derived from biological sources.

**The key distinction between organic and inorganic compounds lies in their chemical bonding and reactivity.**

Carbon dioxide (CO2) is an inorganic compound because it does not fit the traditional definition of organic compounds. It is a molecule composed of one carbon atom double-bonded to two oxygen atoms. The absence of carbon-hydrogen bonds is a critical factor in classifying CO2 as inorganic. Organic compounds are characterized by their carbon-hydrogen bonds, which are essential for the classification of a compound as organic.

Furthermore, the bond energy of the carbon-oxygen bonds in CO2 is indeed higher than that of typical carbon-hydrogen bonds found in organic compounds. This results in CO2 being more stable and less reactive compared to many organic compounds. The higher bond energy contributes to CO2's inertness and its role as a stable end product in various biochemical processes, such as cellular respiration.

It is also important to note that the polarity of the bonds in CO2 plays a role in its classification. The molecule is linear and symmetrical, with the two oxygen atoms pulling electron density away from the central carbon atom. This creates a molecule that, while polar, does not have a net dipole moment because the individual bond dipoles cancel each other out. This lack of a net dipole moment contrasts with many organic molecules, which often have regions of localized charge due to the presence of electronegative atoms like oxygen and nitrogen bonded to carbon.

Another aspect to consider is the reactivity of CO2. Organic compounds are often more reactive due to the presence of functional groups that can participate in various chemical reactions. CO2, on the other hand, is relatively unreactive under standard conditions. It does not readily engage in the types of reactions that are typical of organic compounds, such as substitution, addition, or elimination reactions.

Lastly, the context of chemical reactions is also a factor. Organic chemistry is characterized by a wide range of reactions that involve the formation and breaking of carbon-carbon and carbon-hydrogen bonds. CO2 does not readily participate in these types of reactions, which further supports its classification as an inorganic compound.

In summary, carbon dioxide is considered inorganic because it lacks the defining features of organic compounds, namely the presence of carbon-hydrogen bonds, and it exhibits different chemical properties, such as higher bond energy, polarity, and reactivity, that are characteristic of inorganic substances.

The answer is because organic molecules don't just contain carbon. They contain hydrocarbons or carbon bonded to hydrogen. The C-H bond has a lower bond energy than the carbon-oxygen bond in carbon dioxide, making carbon dioxide (CO2) more stable/less reactive than the typical organic compound.Aug 31, 2017read more >>
