Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
In mass spectrometry, the molecular mass of a small molecule is usually reported as the monoisotopic mass: that is, the mass of the molecule containing only the most common isotope of each element. This also differs subtly from the molecular mass in that the choice of isotopes is defined and thus is a single specific molecular mass out of the ...
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
Ethanethiol, commonly known as ethyl mercaptan, is an organosulfur compound with the formula CH 3 CH 2 SH. [5] It is a colorless liquid with a distinct odor. Abbreviated EtSH, it consists of an ethyl group (Et), CH 3 CH 2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with sulfur in place of oxygen. The odor of ...
Trifluoroethanol is used as a specialized solvent in organic chemistry. [2] [3] Oxidations of sulfur compounds using hydrogen peroxide are effectively conducted in TFE. [4] It competitively inhibits alcohol dehydrogenase for example. [5] TFE forms complexes with Lewis bases such as THF or pyridine through hydrogen bonding, yielding 1:1 adducts. [6]
