    en.wikipedia.org/wiki/Alkylidene_group

    In organic chemistry, alkylidene is a general term for divalent functional groups of the form R 2 C=, where each R is an alkane or hydrogen. [1] They can be considered the functional group corresponding to mono- or disubstituted divalent carbenes (known as alkylidenes), [2] or as the result of removing two hydrogen atoms from the same carbon atom in an alkane.

    Carbon is the sixth element, with a ground-state electron configuration of 1s 2 2s 2 2p 2, of which the four outer electrons are valence electrons. Its first four ionisation energies, 1086.5, 2352.6, 4620.5 and 6222.7 kJ/mol, are much higher than those of the heavier group-14 elements.

  5. Pentadiene - Wikipedia

    en.wikipedia.org/wiki/Pentadiene

    In organic chemistry, pentadiene is any hydrocarbon with an open chain of five carbons, connected by two single bonds and two double bonds. All those compounds have the same molecular formula C 5 H 8. The inventory of pentadienes include: 1,2-pentadiene, or ethyl allene, H 2 C=C=CH−CH 2 −CH 3. [1] 1,3-pentadiene, H 2 C=CH−CH=CH−CH 3 ...

  6. Catenation - Wikipedia

    en.wikipedia.org/wiki/Catenation

    A nonane molecule, consisting of nine carbon atoms in a chain with 20 hydrogen atoms surrounding it. In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. [1] A chain or a ring may be open if its ends are not bonded to each other (an open-chain compound), or closed if they are bonded in a ring (a ...

    The carbon atoms are in the same locations as the silicon and aluminum atoms of the mineral sodalite. The space group, I 4 3m, is the same as the fully expanded form of sodalite would have if sodalite had just silicon or just aluminum. [30] bct-carbon: Body-centered tetragonal carbon was proposed by theorists in 2010. [31] [32]
