  2. Carbon–hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbonhydrogen_bond

    Carbonhydrogen bond. In chemistry, the carbon-hydrogen bond ( C−H bond) is a chemical bond between carbon and hydrogen atoms that can be found in many organic compounds. [ 1] This bond is a covalent, single bond, meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells ...

  3. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    Hydrocarbon. Ball-and-stick model of the methane molecule, CH 4. Methane is part of a homologous series known as the alkanes, which contain single bonds only. In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [1] : 620 Hydrocarbons are examples of group 14 hydrides.

  4. Hydrogen - Wikipedia

    en.wikipedia.org/wiki/Hydrogen

    Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H2, sometimes called dihydrogen, [ 11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen. It is colorless, odorless, tasteless, [ 12] non-toxic ...

  5. List of straight-chain alkanes - Wikipedia

    en.wikipedia.org/wiki/List_of_straight-chain_alkanes

    List of straight-chain alkanes. The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1][ 2] Number of C atoms. Number of isomers [ 3][ 4]

  6. Carbon - Wikipedia

    en.wikipedia.org/wiki/Carbon

    Carbon is the fourth most abundant chemical element in the observable universe by mass after hydrogen, helium, and oxygen. Carbon is abundant in the Sun, stars, comets, and in the atmospheres of most planets. [53] Some meteorites contain microscopic diamonds that were formed when the Solar System was still a protoplanetary disk. [54]

  7. Methane - Wikipedia

    en.wikipedia.org/wiki/Methane

    Methane ( US: / ˈmɛθeɪn / METH-ayn, UK: / ˈmiːθeɪn / MEE-thayn) is a chemical compound with the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.

  8. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

  9. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    Alkane. In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings ), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carboncarbon bonds are single. [ 1] Alkanes have the general chemical formula CnH2n+2.
