Definition Thiols are organic compounds with the general structure R-SH. They are sulfur analogs of alcohols (R-OH). R can be aliphatic or aromatic. The simplest aliphatic representative is methanethiol, the simplest aromatic is thiophenol (analogue of phenol). Thiols are formally derived from hydrogen sulfide (H2S), in which a hydrogen atom has been replaced by a … Thiols
Definition Aldehydes are organic compounds with the general structure R-CHO, where R can be aliphatic and aromatic. The functional group consists of a carbonyl group (C=O) with a hydrogen atom attached to its carbon atom. In formaldehyde, R is a hydrogen atom (HCHO). Aldehydes can be obtained, for example, by oxidation of alcohols or by … Aldehydes
Definition Ketones are organic compounds containing a carbonyl group (C=O) with two aliphatic or aromatic radicals (R1, R2) attached to its carbon atom. In aldehydes, one of the radicals is a hydrogen atom (H). Ketones can be synthesized, for example, by oxidation of alkoles. The simplest representative is acetone. Nomenclature Ketones are usually named with … Ketones
Definition Amides are organic compounds containing a carbonyl group (C=O) whose carbon atom is bonded to a nitrogen atom. They have the following general structure: R1, R2 and R3 can be aliphatic and aromatic radicals or hydrogen atoms. Amides can be synthesized with a carboxylic acid (or a carboxylic acid halide) and an amine using … Amide
Definition Esters are organic compounds formed by the reaction of an alcohol or phenol and an acid such as a carboxylic acid. The condensation reaction releases a water molecule. The general formula of esters is: esters can also be formed with thiols (thioesters), with other organic acids, and with inorganic acids such as phosphoric acid … Ester
Definition Phenols are organic compounds consisting of aromatics bearing one or more hydroxyl groups (Ar-OH). The simplest representative is phenol: this in contrast to alcohols, which are bonded to an aliphatic radical. For example, benzyl alcohol is an alcohol and not a phenol. Nomenclature The names of phenols are formed with the suffix –phenol, e.g., … Phenols
Definition Molecules are defined chemical compounds in which at least two, but usually more, atoms are covalently bonded together. Typical atoms in molecules are nonmetals such as carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), phosphorus (P), and halogens (fluorine (F), chlorine (Cl), bromine (I), iodine (I)). Organic compounds contain carbon atoms. The … Molecules
Definition Alkanes are organic compounds composed exclusively of carbon and hydrogen atoms. They belong to the hydrocarbons and contain only C-C and C-H bonds. Alkanes are not aromatic and saturated. They are referred to as aliphatic compounds. The general formula of acyclic alkanes is C n H 2n+2 . The simplest alkanes are the linear … Alkanes
Definition Alkenes are organic compounds which contain double bonds between carbon atoms (C=C). Alkenes are hydrocarbons, meaning that they consist exclusively of carbon and hydrogen atoms. They are also called unsaturated compounds. This is in contrast to the saturated ones, which contain only single bonds (C-C). Alkenes can be linear (acyclic) or cyclic. Cycloalkenes are, … Alkenes
Definition Alcohols are a group of organic compounds with the general chemical structure R-OH. The hydroxyl group (OH) is attached to an aliphatic carbon atom. Aromatic alcohols are called phenols. They are a separate group of substances. Alcohols can be obtained as derivatives of water (H 2 O) in which a hydrogen atom has been … Alcohols
Products Pure monosaccharides are available in specialty stores, such as pharmacies and drugstores. The best-known monosaccharides include glucose (grape sugar), fructose (fruit sugar) and galactose (mucilage sugar). Structure and properties Monosaccharides are the simplest carbohydrates (“sugars”), consisting of carbon (C), hydrogen (H), and oxygen (O) atoms. The organic compounds have the general formula Cn(H2O)n. There … Monosaccharides
