  3. Methylene group - Wikipedia

    en.wikipedia.org/wiki/Methylene_group

    The group may be represented as −CH 2 − or >CH 2, where the '>' denotes the two bonds. This stands in contrast to a situation where the carbon atom is bound to the rest of the molecule by a double bond, which is preferably called a methylidene group, represented =CH 2. [2] Formerly the methylene name was used for both isomers.

    [CH 2] 2• (X̃ 3 B 1) + H 2 O → [CH 3] • + [HO] • [CH 2] (ã 1 A 1) + H 2 O → H 2 CO + H 2 or H 3 COH. The singlet state is also more stereospecific than the triplet. [10] Methylene spontaneously autopolymerises to form various excited oligomers, the simplest of which, is the excited form of the alkene ethylene. The excited oligomers ...

  5. Chemical formula - Wikipedia

    en.wikipedia.org/wiki/Chemical_formula

    In ethylene there is a double bond between the carbon atoms (and thus each carbon only has two hydrogens), therefore the chemical formula may be written: CH 2 CH 2, and the fact that there is a double bond between the carbons is implicit because carbon has a valence of four. However, a more explicit method is to write H 2 C=CH 2 or less ...

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

  8. Formula - Wikipedia

    en.wikipedia.org/wiki/Formula

    In modern chemistry, a chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols, numbers, and sometimes other symbols, such as parentheses, brackets, and plus (+) and minus (−) signs. [9] For example, H 2 O is the chemical ...

    en.wikipedia.org/wiki/Methine_group

    Methine or methylylidene (IUPAC) In organic chemistry, a methine group or methine bridge is a trivalent functional group =CH−, derived formally from methane.It consists of a carbon atom bound by two single bonds and one double bond, where one of the single bonds is to a hydrogen.
