In one isomer the CO ligands are terminal. When a pair of CO are bridging, cis and trans isomers are possible depending on the location of the C 5 H 5 groups. [7] Another example in organometallic chemistry is the linkage isomerization of decaphenylferrocene, [(η 5-C 5 Ph 5) 2 Fe]. [8] [9] Formation of decaphenylferrocene from its linkage isomer
In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers.
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 ...

Care must be taken to avoid cocrystallisation of the ortho isomer. [2] Many nitro compounds' ortho and para isomers have quite different boiling points. These isomers can often be separated by distillation. These separated isomers can be converted to diazonium salts and used to prepare other pure ortho or para compounds. [3]
It may occur as either the cis (Z) or trans (E) isomer. Trans (E) isoeugenol is crystalline while cis (Z) isoeugenol is a liquid. [ 6 ] Isoeugenol is one of several phenolic compounds responsible for the mold-inhibiting effect of smoke on meats and cheeses.
Isotopomers or isotopic isomers are isomers which differ by isotopic substitution, and which have the same number of atoms of each isotope but in a different arrangement. For example, CH 3 OD and CH 2 DOH are two isotopomers of monodeuterated methanol .
