What are the general reactions of the heterocyclic compounds?

Answer 1

Aromatic heterocycles normally undergo #"aromatic heterocyclic substitution."#

Additionally, entire textbooks have been written about their reactivity; you will need to refer to your text.

#"Pyrrole,"# #C_5H_4NH#; #"furan,"# #C_5H_4NO#; and #"thiophen,"# #C_5H_4S#, are so-called #pi-"excessive"# aromatic heterocycles because the lone-pairs on the heteroatom is delocalized around the ring, making these species MUCH more nucleophilic than the benzene system.

The general reactions of heterocyclic compounds include substitution, addition, oxidation, reduction, and ring-opening or ring-closing reactions. These reactions can lead to the formation of new functional groups, changes in ring size, and alterations in the properties of the heterocyclic compound. Additionally, heterocyclic compounds may undergo aromaticity-preserving reactions, where the aromaticity of the ring is maintained throughout the reaction process.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
