Isoprene, or 2-methyl-1,3-butadiene, is a common volatile organic compound with the formula CH 2 =C(CH 3)−CH=CH 2. In its pure form it is a colorless volatile liquid.
The terms "polar" and "nonpolar" are usually applied to covalent bonds, that is, bonds where the polarity is not complete. To determine the polarity of a covalent bond using numerical means, the difference between the electronegativity of the atoms is used.
Terpenes are colorless, although impure samples are often yellow. Boiling points scale with molecular size: terpenes, sesquiterpenes, and diterpenes respectively at 110, 160, and 220 °C. Being highly non-polar, they are insoluble in water. Being hydrocarbons, they are highly flammable and have low specific gravity (float on water).
Phytane is a non-polar organic compound that is a clear and colorless liquid at room temperature. It is a head-to-tail linked regular isoprenoid with chemical formula C 20 H 42. [2] Phytane has many structural isomers.
They are usually organized into a bilayer in membranes with the polar hydrophilic heads sticking outwards to the aqueous environment and the non-polar hydrophobic tails pointing inwards. [6] Glycerophospholipids consist of various diverse species which usually differ slightly in structure. The most basic structure is a phosphatidate.
The separation of β-carotene from the mixture of other carotenoids is based on the polarity of a compound. β-Carotene is a non-polar compound, so it is separated with a non-polar solvent such as hexane. [13] Being highly conjugated, it is deeply colored, and as a hydrocarbon lacking functional groups, it is lipophilic.
Constitution formula for isomers of C 5 H 8 with CAS numbers. The molecular formula C 5 H 8 may refer to any of the following hydrocarbons: . Pentynes:; 1-Pentyne; 2-Pentyne; 3-Methyl-1-butyne or isopentyne, CAS 598-23-2
Citral is an acyclic monoterpene aldehyde. Being a monoterpene, it is made of two isoprene units.Citral is a collective term which covers two geometric isomers that have their own separate names; the E-isomer is named geranial (trans-citral; α-citral [2]) or citral A.
