Oct 30, 2017 · "Organic" may be one of the most confusing words in language today. Although most people will probably have a vague idea of the meaning of the term they probably won't know the definition. Part of the confusion arises from the fact that there are two, very different, definitions for the same word, one from chemistry and one from agriculture.

The main difference between the two classes of substances is that organic compounds always contain the element carbon, while most inorganic compounds lack this element. Because there are carbon-containing inorganic compounds, the presence of carbon is not sufficient to classify a compound as organic! With very few exceptions, organic compounds cont...
Compounds made within living organisms are organic molecules. The main classes of organic compounds are carbohydrates, fats, proteins, and nucleic acids. Examples of organic substances include: 1. Sucrose (table sugar), C12H22O11 2. Methane, CH4 3. DNA 4. Benzene, C6H6 5. Ethanol (grain alcohol), C2H6O 6. Coal 7. Hair and fingernails (keratin prote...
There are a few organic compounds containing carbon, but no C-H bond. Examples include: 1. Carbon tetrachloride, CCl4 2. Urea, CO(NH2)2
Inorganic substances include all pure elements, salts, many acids and bases, metals and alloys, and minerals. Compounds in which a non-carbon atom forms a chemical bond with hydrogen are inorganic. Examples of inorganic compounds include: 1. Sodium chloride (table salt) (NaCl) 2. Brass 3. Glass and quartz (SiO2) 4. Hydrochloric acid (HCl) 5. Sulfur...
A few inorganic compounds contain carbon. These include the oxides, carbides, some carbonates, and some cyanides, Examples include: 1. Carbon dioxide (CO2) 2. Cyanides (C-N bond) 3. Carbides (e.g., boron carbide, B4C) 4. Carbon disulfide (CS2) 5. Phosgene (COCl2) Note the hydrogen cyanide, HCN, contains both carbon and hydrogen. It is usually consi...
Pure elements are not compounds, so they are neither organic nor inorganic compounds: 1. Argon (Ar) 2. Silver (Ag) 3. Sulfur (S) 4. Carbon (C)
Most organic compounds are made within living organisms, but the molecules may form via other processes. For example, organic compounds found on Mars or within a nebula aren’t necessarily signs of extraterrestrial life. Solar radiation can supply the energy needed to convert inorganic compounds into organics.

The 17th century chemists were not that far off. Carbon is the essence of life. Every life form, as well as the molecules that make life possible all contain carbon, for example, proteins, DNA/RNA, and amino acids.
Jul 22, 2024 · The word "organic" means something very different in chemistry than it does when you're talking about produce and food. Organic compounds and inorganic compounds form the basis of chemistry. The primary difference between organic vs. inorganic compounds is that organic compounds always contain carbon while most inorganic compounds do not contain carbon.

Oct 7, 2021 · Chemists refer to most molecules that contain one or more carbon atoms as organic. The study of these molecules is organic chemistry. Carbon-based molecules get special attention because no other element comes close to carbon’s versatility. More types of carbon-based molecules exist than all non-carbon ones put together.
Define organic chemistry. Identify organic molecules as alkanes, alkenes, alkynes, alcohols, or carboxylic acids. Organic chemistry is the study of the chemistry of carbon compounds. Carbon is singled out because it has a chemical diversity unrivaled by any other chemical element. Its diversity is based on the following:

Jan 8, 2018 · In chemistry, the definition is based solely on chemical structure. With very few exceptions, a chemical is classified as organic if it contains at least one carbon atom, regardless of its source. This is why organic chemistry is called “the chemistry of carbon.”. Generally, that carbon atom is bonded to at least one hydrogen atom.
