Przykłady double bond

• This double bond is located between the fourth and fifth carbon atoms of the 18-carbon sphingoid base.

• Note the addition of a restraining olefin (double bond) bridge in (g).

• It is initiated by free-radical attack upon a lipid, resulting in the removal of a hydrogen atom from a methylene group adjacent to a double bond.

• Saturated cyclic compounds contain single bonds only, whereas aromatic rings have an alternating (or conjugated) double bond.

• This compound features a rare example of a stable, unhindered carbon-selenium double bond.

• They have a long and flexible chain between the onium heads, except for the double bond of mivacurium.

• Each contains one double bond within its molecular structure.

• The compound is deprotonated on one side and protonated on another side, whereas a single bond and a double bond are exchanged.

• Each double bond has two additional localized electrons, while each triple bond has four additional electrons (two pairs) between the bonded atoms.

• Oxidation at the double bond occurs slowly in air, and is known as rancidification in foodstuffs or drying in coatings.

• The overall transformation is the conversion of the carbonsulfur bonds to a carboncarbon double bond.

• Due to the nature of elimination, it can be applied to both small rings, and large rings containing a double bond.

• The aldehydic carbon-oxygen double bond can also be subject to hydroformylation, which leads to formic acid and its esters.

• These materials exist as "cis" or "trans" isomers depending on the geometry of the double bond.

• Alkenes with a thiol group on both sides of the double bond are called enedithiols.
