Nucleophilic Substitution Reactions at the Saturated C Atom,The book began with chemistry that is by no means uncommon, but the bulk of organic chemistry has and continues to be based on two electron processes. Substitution reactions comprise one class of reactions involving such chemistry. Addition reactions comprise the other. You should have been introduced to both by now.

,-Eliminations,emoved in such a way that they do not become constituents of same molecule. In other eliminations, they become attached to one another such that they leave as a molecule of type X-Y or X=Y or as X≡Y. The atoms or groups X and Y can be bound to C atoms and/or to heteroatoms in the substrate. These atoms can be ..- or ..-hybridized.

Carbonic Acid Derivatives and Heterocumulenes and Their Interconversion,.). They can be regarded as anhydrides of the carbonic acid derivatives .. In fact, heterocumulenes are typically generated by eliminating water from such carbonic acid derivatives. Sometimes this occurs spontaneously, especially at elevated temperatures, but generally only upon treatment with a dehydrating reagent.
