The π-bond in the ethylene molecule is responsible for its useful reactivity. The double bond is a region of high electron density , thus it is susceptible to attack by electrophiles . Many reactions of ethylene are catalyzed by transition metals, which bind transiently to the ethylene using both the π and π* orbitals.
Four-carbon molecules are based on a skeleton made from four carbon atoms. They may be in a chain, branched chains, cycles or even bicyclic compounds C 4 H 4 isomers with CAS registry numbers
The Simplified Molecular Input Line Entry System (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H.It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block.
It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [ 12 ] non-toxic, and highly combustible .
Chemical synthesis employs various strategies to achieve efficient, precise, and molecular transformations that are more complex than simply converting a reactant A to a reaction product B directly. These strategies can be grouped into approaches for managing reaction sequences. Reaction Sequences:
Typically these have a metal, such as a copper ion, in the center and a nonmetals atom, such as the nitrogen in an ammonia molecule or oxygen in water in a water molecule, forms a dative bond to the metal center, e.g. tetraamminecopper(II) sulfate [Cu(NH 3) 4]SO 4 ·H 2 O. The metal is known as a "metal center" and the substance that ...
Cyclobutane is a cycloalkane and organic compound with the formula (CH 2) 4.Cyclobutane is a colourless gas and is commercially available as a liquefied gas.Derivatives of cyclobutane are called cyclobutanes.
