The molecular formula C 4 H 8 (molar mass: 56.11 g/mol) may refer to: Butenes (butylenes) 1-Butene, or 1-butylene; 2-Butene; Isobutylene; Cyclobutane; Methylcyclopropane
Isobutylene is used in the production of a variety of products. It is alkylated with butane to produce isooctane or dimerized to diisobutylene (DIB) and then hydrogenated to make isooctane, a fuel additive. Isobutylene is also used in the production of methacrolein.
alkyne (unsaturated) vs alkane (saturated) arene (unsaturated) vs cycloalkane (saturated) For organic compounds containing heteroatoms (other than C and H), the list of unsaturated groups is long but some common types are: carbonyl, e.g. ketones, aldehydes, esters, carboxylic acids (unsaturated) vs alcohol or ether (saturated) nitrile ...
Crotonic acid has 4 carbons, is included in croton oil, and is a trans-2-mono-unsaturated fatty acid. C 3 H 5 CO 2 H, IUPAC organization name (E)-but-2-enoic acid, trans-but-2-enoic acid, numerical representation 4:1, n-1, molecular weight 86.09, melting point 72–74 °C, boiling point 180–181 °C, specific gravity 1.027. CAS registry number ...
In the above example [4.2.0]-bicyclooctane would be written bicyclo[4.2.0]octane to fit the conventions for IUPAC naming. It then has room for an additional numerical prefix if there is the need to include details of other attachments to the molecule such as chlorine or a methyl group.
Margaric acid with its seventeen carbon atoms is an important odd-chain fatty acid. Odd-chain fatty acids are those fatty acids that contain an odd number of carbon atoms. In addition to being classified according to their saturation or unsaturation, fatty acids are also classified according to their odd or even numbers of constituent carbon atoms.
Some are unsaturated and some are branched. They are widely used in industry. As with fatty acids, they are often referred to generically by the number of carbon atoms in the molecule, such as "a C 12 alcohol", that is an alcohol having 12 carbons, for example dodecanol .
An α,β-unsaturated acid is a type of α,β-unsaturated carbonyl compound that consists of an alkene conjugated to a carboxylic acid. [3] The simplest example is acrylic acid ( CH 2 =CHCO 2 H ). These compounds are prone to polymerization, giving rise to the large area of polyacrylate plastics.
