1,4-Cyclohexadiene is an organic compound with the formula C 6 H 8. It is a colourless, flammable liquid that is of academic interest as a prototype of a large class of related compounds called terpenoids, an example being γ-terpinene. An isomer of this compound is 1,3-cyclohexadiene.
In organic chemistry, Hückel's rule predicts that a planar ring molecule will have aromatic properties if it has 4n + 2 π-electrons, where n is a non-negative integer. The quantum mechanical basis for its formulation was first worked out by physical chemist Erich Hückel in 1931. [1] [2] The succinct expression as the 4n + 2 rule has been ...
In organic chemistry, a cycloalkene or cycloolefin is a type of alkene hydrocarbon which contains a closed ring of carbon atoms and either one or more double bonds, but has no aromatic character. Some cycloalkenes, such as cyclobutene and cyclopentene , can be used as monomers to produce polymer chains. [ 1 ]
Cyclohexadiene may refer to: Cyclohexa-1,3-diene, Cyclohexa-1,4-diene, See also. Benzene or its theoretical isomer 1,3,5-Cyclohexatriene; Cyclohexene
The molecular formula C 6 H 8 may refer to: Cyclohexadiene (disambiguation) 1,3-Cyclohexadiene; 1,4-Cyclohexadiene; Methylcyclopentadiene; Propellane; The standard composition of gasoline (a mixture of different hydrocarbons) is approximately equivalent to C 6 H 8
In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron.The bond angles are arccos(− 1 / 3 ) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) [1] [2] as well as its heavier analogues.
The molecule must be planar. The molecule must have a complete conjugated π-electron system within the ring. The molecule must have 4n π-electrons where n is any integer within the conjugated π-system. This differs from aromaticity only in the fourth criterion: aromatic molecules have 4n +2 π-electrons in the conjugated π system and ...
Tetracyanoquinodimethane (TCNQ) is an organic compound with the chemical formula (N≡C−) 2 C=C 6 H 4 =C(−C≡N) 2. It is an orange crystalline solid. This cyanocarbon, a relative of para-quinone, is an electron acceptor that is used to prepare charge transfer salts, which are of interest in molecular electronics.
