On the mathematical theory of isomers
WebOne interaction of mathematics and chemistry that is so familiar now that it is taken for granted, is the way certain quantities are balanced or preserved when a chemical reaction occurs. In a chemical reaction the masses of the inputs to the reaction must be the same as the masses of the products produced by the reaction.

WebA simple and fast algorithm for enumerating alkene isomers is described. This algorithm is based on a 2-step hypothetical chemical reaction. In the first step, an alkane molecule … WebI've been looking for a formula determining the number of possible isomers for a given organic compound. As such formula does not exist I though I could do a little investigation on my own. I looked at alkanes: Structural formulas of alkanes may be represented as graphs. For instance, propane: can be represented as: (source: chemistry-reference ...
WebJournal of Discrete Mathematical Sciences and Cryptography 2024 Abstract The mathematical chemistry is the part of theoretical chemistry which is concerned with … Webresearch in calculating the number of isomers. For example, in 1874 the number of isomers of a chemical compound with many Cayley graph concept. The research was continued by George Polya by using combinatorial to determine the number of isomers of a chemical compound. Polya theory is very relevant for this
WebBlair algorithm. By using this simple algorithm, the numbers of constitutional isomers of alkenes and alkynes for carbon content greater than 30 are easily enumerated. In addition, through this algorithm, a mathematical relationship between the number of constitutional isomers of alkenes and alkynes has been established for the first time.

In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
