[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.
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.

In chemistry, dioxirane (systematically named dioxacyclopropane, also known as methylene peroxide or peroxymethane) is an organic compound with formula CH 2 O 2.The molecule consists of a ring with one methylene and two oxygen atoms.
1,3-Dioxane or m-dioxane is an organic compound with the molecular formula (CH 2) 4 O 2. It is a saturated six-membered heterocycle with two oxygen atoms in place of carbon atoms at the 1- and 3- positions. 1,4-Dioxane, which is of greater commercial value, is an isomer. Both dioxanes are colorless liquids. [1]
Ethylene dione or ethylenedione, also called dicarbon dioxide, Carbon peroxide, ethenedione, or ethene-1,2-dione, is a chemical compound with the formula C 2 O 2 or O=C=C=O. It is an oxide of carbon (an oxocarbon ), and can be described as the carbon-carbon covalent dimer of carbon monoxide . [ 1 ]

Cyclopropane was discovered in 1881 by August Freund, who also proposed the correct structure for the substance in his first paper. [4] Freund treated 1,3-dibromopropane with sodium, causing an intramolecular Wurtz reaction leading directly to cyclopropane. [5]
Tetracarbon dioxide is an oxide of carbon, a chemical compound of carbon and oxygen, with chemical formula C 4 O 2 or O=C=C=C=C=O. It can be regarded as butatriene dione , the double ketone of butatriene — more precisely 1,2,3-butatriene-1,4-dione .
