Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which compound is inorganic?
A
glucose (C6Hl2O6)
B
carbon dioxide (CO2)
C
ethane (C2H6)
D
stearic acid (Cl8H36O2)
Explanation: 

Detailed explanation-1: -Carbon dioxide, CO2, is another example of an inorganic compound because it does not contain both carbon and hydrogen. One molecule of CO2 contains one atom of carbon and two atoms of oxygen. There are a total of three atoms in one molecule of carbon dioxide, CO2.

Detailed explanation-2: -Currently, organic compounds are defined as covalently bonded compounds containing carbon, excluding carbonates and oxides. By this definition, compounds such as carbon dioxide (CO2) and sodium carbonate (Na2CO3) are considered to be inorganic. Organic chemistry is the study of all organic compounds.

Detailed explanation-3: -They contain hydrocarbons or carbon bonded to hydrogen. But in carbondioxide, it is not present, so it is not an organic compound.

Detailed explanation-4: -An inorganic compound is a substance that does not contain both carbon and hydrogen. A great many inorganic compounds do contain hydrogen atoms, such as water (H2O) and the hydrochloric acid (HCl) produced by your stomach. In contrast, only a handful of inorganic compounds contain carbon atoms.

Detailed explanation-5: -The answer is because organic molecules don’t just contain carbon. They contain hydrocarbons or carbon bonded to hydrogen. The C-H bond has lower bond energy than the carbon-oxygen bond in carbon dioxide, making carbon dioxide (CO2) more stable/less reactive than the typical organic compound.
