In chemistry , an inorganic compound is typically a chemical compound that lacks carbon-hydrogen bonds , that is, a compound that is not an organic compound . However, the distinction is not clearly defined; Officials have different views on this subject.    The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry .
Inorganic compounds comprise most of the Earth’s crust , although the compositions of the deep mantle are active areas of investigation. Some simple compounds containing carbon are often considered inorganic. Examples include the following salts of carbon monoxide , carbon dioxide , carbides , and inorganic cations : carbonates , cyanides , cyanates , and thiocyanates . These are normal parts of most organic systems, including many organisms ; Describing a chemical as inorganic does not mean that it does not occur within living things.
Friedrich Wöller ‘s conversion of ammonium cyanate into urea in 1828 is often cited as his starting point in modern organic chemistry .    In Wöhler’s era, there was widespread belief that organic compounds contained an important spirit . In the absence of vitalism, the distinction between inorganic and organic chemistry is only meaningful.
- The Inorganic Crystal Structure Database (ICSD) in its definition of “inorganic” carbon compounds, states that such compounds may contain either C- H or C-C bonds, but not both. 
- The book series Inorganic Synthesis does not define inorganic compounds. Most of its content belongs to the metal complexes of organic ligands. 
- IUPAC does not provide a definition of “inorganic” or “inorganic compound”, but defines inorganic polymer as “…the skeletal structure that does not contain a carbon atom”.
What is the difference between organic and inorganic compound?
Organic Compounds: Organic compounds are compounds that essentially contain carbon atoms in structure along with atoms such as hydrogen, nitrogen, and oxygen. Inorganic Compounds: Inorganic compounds are compounds that do not essentially contain carbon atoms in their structure.
Which is an inorganic chemical?
Inorganic chemistry is one of the three branches of ‘chemistry’. The field of ‘inorganic chemistry’ is to ‘measure’ all the elements and many compounds except carbon. Elements like boron, silicon, germanium, etc. also form almost the same variety of compounds as carbon.
What are organic compounds?
Compounds of carbon are known as organic compounds. In addition to carbon, most organic compounds also contain hydrogen, oxygen or other elements. For example methane, ethanol, ethane, ethene, ethene, etc.
What are organic and inorganic substances?
Organic matter is organic in nature where as inorganic substances are minerals. There are many organic substances and sources of energy such as petroleum diesel methane ethane on the other hand inorganic substances act as catalysts.
How are organic substances?
Organic compounds are compounds made up of carbon, hydrogen and other elements. There are often covalent bonds between them and they are soluble in organic solutions only. Examples of these are methane, chloroform, acetic acid, carbohydrate, urea, etc. Their presence is more in organic matter.
How many organic compounds are there?
The chemical compounds of carbon are called organic compounds. Their number in nature is more than 10 lakhs.
What is conjugation in organic chemistry?
The terms conjugation and hyperconjugation are related to unsaturated organic compounds. The word conjugation has different meanings in chemistry; Conjugation can refer to the joining of two compounds to form a single compound or it can be the overlap of p-orbitals in a bond (sigma bond).
