Organic chemistry is a branch of chemistry that studies the structure, properties and reactions of organic compounds, which contain carbon in covalent bonding.
Study of structure determines their chemical composition and of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. Organic chemistry is an important and dynamic field, where the number of identified organic compounds are immense and increase each day.
Naming of these organic chemical compounds are made according to the rules defined in IUPAC (International Union of Pure and Applied Chemistry) Nomenclature of Organic Chemistry, a.k.a., Blue book (Favre and Powell, ; IUPAC, ). Ethers are a class of organic compounds that contain an ether group.
An ether group is an oxygen atom connected to two alkyl or aryl groups. They follow the general formula R-O-R’. The C-O-C linkage is characterized by bond angles of degrees, with the C-O distances being about pm. In organic chemistry, functional groups are specific substituents or moieties within molecules that are responsible for the characteristic chemical reactions of those molecules.
The same functional group will undergo the same or similar chemical reaction(s) regardless of the size of the molecule it is a part of. This allows for systematic prediction of chemical reactions and behavior of.
In organic chemistry, a functional group is a set of atoms within molecules that function together to react in predictable ways. Functional groups undergo the same chemical reactions no matter how large or small the molecule is.
Covalent bonds link the atoms within functional groups and connect them to the rest of the molecule. Unlike most organic compounds, dyes possess colour because they 1) absorb light in the visible spectrum (– nm), 2) have at least one chromophore (colour-bearing group), 3) have a conjugated system, i.e.
a structure with alternating double and single bonds, and 4) exhibit resonance of electrons, which is a stabilizing force in organic compounds (Abrahart, ). When any one of these. Chloroethane is the simplest and least toxic member of the class of chloroethanes, that is ethane in which a single hydrogen is substituted by a chlorine.A colourless gas at room temperature and pressure (boiling point 12℃), it is used as a mild topical anaesthetic to numb the skin prior to ear piercing, skin biopsies, etc., and is also used in the treatment of sports injuries.

An organochloride, organochlorine compound, chlorocarbon, or chlorinated hydrocarbon is an organic compound containing at least one covalently bonded atom of chlorine that has an effect on the chemical behavior of the chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) provides common examples.
The wide structural variety and divergent chemical. In organic chemistry, isomers are molecules with the same molecular formula (i.e. the same number of atoms of each element), but different structural or spatial arrangements of the atoms within the molecule.
The reason there are such a colossal number of organic compounds – more than 10 million – is in part down to isomerism. An important achievement of the fluorine group was the preparation of crystals and the first structural determination of xenon–difluoride complex, XeF SbF 5.
With Ray Kemmitt, also in Leicester, Ray Peacock began to try to make transition metal carbonyl fluorides and, again with the help of David Russell, solved the first crystal structure. Cumene (isopropylbenzene) is an organic compound that is based on an aromatic hydrocarbon with an aliphatic substitution.
It is a constituent of crude oil and refined fuels. It is a flammable colorless liquid that has a boiling point of °C. Nearly all the cumene that is produced as a pure compound on an industrial scale is converted to cumene hydroperoxide, which is an intermediate in the Chemical formula: C₉H₁₂.
