The cis isomer in this case has a boiling point of 60.3 °C, while the trans isomer has a boiling point of 47.5 °C. [6] In the cis isomer the two polar C–Cl bond dipole moments combine to give an overall molecular dipole, so that there are intermolecular dipole–dipole forces (or Keesom forces), which add to the London dispersion forces and ...
In organic chemistry, hexene is a hydrocarbon with the chemical formula C 6 H 12. The prefix "hex" is derived from the fact that there are 6 carbon atoms in the molecule, while the " -ene " suffix denotes that there is an alkene present—two carbon atoms are connected via a double bond .
2-Hexyne can be semihydrogenated to yield 2-hexene or fully hydrogenated to hexane. [3] With appropriate noble metal catalysts it can selectively form cis-2-hexene. [4] 2-Hexyne can act as a ligand on gold atoms. [5] With strong sulfuric acid, the ketone 2-hexanone is produced. However this reaction also causes polymerization and charring. [6]

On checking the references in the article, the cis isomer boiling point is given in Ref.2 (Akros data) as 145oC at an unstated pressure - without checking further one would normally assume a normal boiling point at 1 atm. The trans isomer boiling point however is given in Ref.3 (Organic synthesis) as 75oC at a reduced pressure of 78 Torr (mm).
cis-3-Hexenal, also known as (Z)-3-hexenal and leaf aldehyde, is an organic compound with the formula CH 3 CH 2 CH=CHCH 2 CHO. It is classified as an unsaturated aldehyde . It is a colorless liquid and an aroma compound with an intense odor of freshly cut grass and leaves .
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
trans-1,3-Disubstituted cyclohexanes are like cis-1,2- and cis-1,4- and can flip between the two equivalent axial/equatorial forms. [ 2 ] Cis -1,4-Di- tert -butylcyclohexane has an axial tert -butyl group in the chair conformation and conversion to the twist-boat conformation places both groups in more favorable equatorial positions.
