It was found, however, that condensation products from the three isomers were distinguishable from one another neither in physical nor in tannoid properties.
But it is not only the formation of different isomers which is included in their constitution, but also the different ways in which they will decompose or give other products.
In ordinary isomers indications of mutual transformation often occur; and among these the predominant fact is that denoted as tautomerism or pseudomerism.
The third most valuable indication which molecular structure gives about these isomers is how to prepare them, for instance, that normal hexane, represented by CH3.
In reality such tautomeric compounds are apparently a mixture of two isomersin equilibrium, and indeed in some cases both forms have been isolated; then one speaks of desmotropy (Gr.
The one group included thoseisomers where the identity in composition was accompanied by identity in molecular weight, i.
It is found thatisomers have nearly the same critical volume, and that equal differences in molecular content occasion equal differences in critical volume.
Formula (4) is symmetrical and based on Kekule's formula: it is in full accord with the syntheses and decompositions of the naphthalene nucleus and the number of isomers found.
A factor of considerable importance in determining boiling-points of isomers is the symmetry of the molecule.
In the case of tetra-substituted compounds, thirty isomers are possible when all the groups are different.
The next members are the isomers anthracene and phenanthrene, C14H10, formed from three benzene nuclei.
There is more than one amylic alcohol according to theory; eight isomers are possible, and seven are known.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "isomers" in a variety of sentences. We hope that you will now be able to make sentences using this word.
