The formula for degree of unsaturation is: = + where n i is the number of atoms with valence v i. [2] That is, an atom that has a valence of x contributes a total of x − 2 to the degree of unsaturation. The result is then halved and increased by 1.
A saturated compound is a chemical compound (or ion) that resists addition reactions, such as hydrogenation, oxidative addition, and binding of a Lewis base. The term is used in many contexts and for many classes of chemical compounds. Overall, saturated compounds are less reactive than unsaturated compounds.
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.
A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. A saturated fat has no carbon-to-carbon double bonds, so the maximum possible number of hydrogen is bonded to carbon, and thus, is considered to be "saturated" with hydrogen atoms.
Today, adamantane is an affordable chemical compound with a cost of one or two USD per gram. All the above methods yield adamantane as a polycrystalline powder. Using this powder, single crystals can be grown from the melt, solution, or vapor phase (e.g. with the Bridgman–Stockbarger technique). Melt growth results in the worst crystalline ...
Iodine numbers are often used to determine the degree of unsaturation in fats, oils and waxes. In fatty acids, unsaturation occurs mainly as double bonds which are very reactive towards halogens, the iodine in this case. Thus, the higher the iodine value, the more unsaturations are present in the fat. [1]

1,3-Dibromopropane is an organobromine compound with the formula (CH 2) 3 Br 2. It is a colorless liquid with sweet odor. It is used in organic synthesis to form C 3-bridged compounds such as through C-N coupling reactions. 1,3-Dibromopropane was used in the first cyclopropane synthesis in 1881, known as the Freund reaction.
