  2. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    [1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

    en.wikipedia.org/wiki/Structural_formula

    Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

  5. Ethanol - Wikipedia

    en.wikipedia.org/wiki/Ethanol

    Ethanol is a 2-carbon alcohol. Its molecular formula is CH 3 CH 2 OH. The structure of the molecule of ethanol is CH 3 −CH 2 −OH (an ethyl group linked to a hydroxyl group), which indicates that the carbon of a methyl group (CH 3 −) is attached to the carbon of a methylene group (−CH 2 –), which is

  6. Primary alcohol - Wikipedia

    en.wikipedia.org/wiki/Primary_alcohol

    A primary alcohol is an alcohol in which the hydroxy group is bonded to a primary carbon atom. It can also be defined as a molecule containing a “–CH 2 OH” group. [ 1 ] In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR 2 OH”, where “R” indicates a carbon-containing group.

  8. Dicarboxylic acid - Wikipedia

    en.wikipedia.org/wiki/Dicarboxylic_acid

    Dicarboxylic acids where the carboxylic groups are separated by none or one carbon atom decompose when they are heated to give off carbon dioxide and leave behind a monocarboxylic acid. [ 26 ] Blanc's Rule says that heating a barium salt of a dicarboxylic acid, or dehydrating it with acetic anhydride will yield a cyclic acid anhydride if the ...

  9. Square pyramidal molecular geometry - Wikipedia

    Structure of xenon oxytetrafluoride, an example of a molecule with the square pyramidal coordination geometry. Square pyramidal geometry describes the shape of certain chemical compounds with the formula ML 5 where L is a ligand. If the ligand atoms were connected, the resulting shape would be that of a pyramid with a square base.
