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

Explanation:

And whole text books have been written about their reactivity, and you are going to have to consult 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.
