  2. Cyclopentane - Wikipedia

    en.wikipedia.org/wiki/Cyclopentane

    Cyclopentane is also used in the manufacture of synthetic resins and rubber adhesives. [citation needed] Cyclopentane is a minor component of automobile fuel, with its share in US gasoline varying between 0.2 and 1.6% in early 1990s [8] and 0.1 to 1.7% in 2011. [9] Its research and motor octane numbers are reported as 101 or 103 and 85 or 86 ...

  3. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

    Cyclopentane (CAS 287-92-3) Methylcyclobutane (CAS 598-61-8) Cyclopropanes. Ethylcyclopropane (CAS 1191-96-4) 1,1-Dimethylcyclopropane (CAS 1630-94-0)

  5. Cyclopentene - Wikipedia

    Cyclopentene was first prepared by Carl Gärtner in 1893 from iodocyclopentane with potassium hydroxide.He named it pentamethenylene (German: Pentamethenylen). [3] ...

  6. Magic acid - Wikipedia

    en.wikipedia.org/wiki/Magic_acid

    It is easily described by Lewis dot structures because it contains only two-electron, single bonds to adjacent carbon atoms. Many tertiary cycloalkyl cations can also be formed in superacidic solutions. One such example is the 1-methyl-1-cyclopentyl cation, which is formed from both the cyclopentane and cyclohexane precursor.

  7. Newman projection - Wikipedia

    en.wikipedia.org/wiki/Newman_projection

    3D structure A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [ 1 ] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.

  8. Lone pair - Wikipedia

    en.wikipedia.org/wiki/Lone_pair

    Lone pairs (shown as pairs of dots) in the Lewis structure of hydroxide. In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond [1] and is sometimes called an unshared pair or non-bonding pair. Lone pairs are found in the outermost electron shell of atoms.

  9. Cyclopentadienyl complex - Wikipedia

    en.wikipedia.org/wiki/Cyclopentadienyl_complex

    All 5 carbon atoms of a Cp ligand are bound to the metal in the vast majority of M–Cp complexes. This bonding mode is called η 5-coordination.The M–Cp bonding arises from overlap of the five π molecular orbitals of the Cp ligand with the s, p, and d orbitals on the metal.
