Hi I m confused that in simple furan why it do not show nucleophilic subtitution reaction. while in subtituted furan show it.
furan though has a lone pair of electron which is not delocalised but due to high electronegetivity of oxygen it is not a available for donation hence has weak basic proerty

Because it has 2 double bonds. An ether might not have any double or triple bonds!

No. It is an aldehyde. Furfural is furan-2-carboxaldehyde.
A benzofurane is another term for a benzofuran - any of a class of bicyclic heterocycles consisting of a benzene ring fused with one of furan.
Furan is more reactive than Pyrrole because it is less stable as it contains an extra lone pair than that of pyrrole, which is available for attack of an acid, results in the destabilization of the ring.
