Are homodesmotic reactions isodesmic reactions?
Yes, homodesmotic reactions are a subset of isodesmic reactions.
An isodesmic reaction is a reaction that has the same number and type of bonds in the reactants and in the products.
An example of an isodesmic reaction is
Homodesmotic reactions are a subclass of isodesmic reactions.
Here, the reactants and products are even more similar. They must contain equal numbers of
- atoms in the same state of hybridization
- groups containing the same number of H atoms.
An example of a homodesmotic reaction is
The reactants and products contain equal numbers of bonds between carbons in the same state of hybridization and hydrogens bound to identical atom types.
