2. Structural formula - Wikipedia

   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 possibly arranged in the real three-dimensional space.

3. Skeletal formula - Wikipedia

   en.wikipedia.org/wiki/Skeletal_formula

   The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...

4. Arrow pushing - Wikipedia

   en.wikipedia.org/wiki/Arrow_pushing

   Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.

5. Organic chemistry - Wikipedia

   en.wikipedia.org/wiki/Organic_chemistry

   Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1] Study of structure determines their structural formula.

6. Fischer projection - Wikipedia

   en.wikipedia.org/wiki/Fischer_projection

   In chemistry, the Fischer projection, devised by Emil Fischer in 1891, is a two-dimensional representation of a three-dimensional organic molecule by projection. Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry. The use of Fischer projections ...

7. Structural theory - Wikipedia

   en.wikipedia.org/wiki/Structural_theory

   According to structural theory, from the structural formula of a molecule it is possible to derive physical and spectroscopic data and to predict chemical reactivity. [ 1 ] Beginning from about 1858, many scientists from several countries took part in the early development of structural theory, including August Kekule , Archibald Scott Couper ...
