A reaction in which a negative ion (nucleophile) attacks on a partially positive carbon atom then reaction is known as nucleophilic reaction, it may be substitution reaction or addition reaction.
Hi I m confused that in simple furan why it do not show nucleophilic subtitution reaction. while in subtituted furan show it.
It depends upon incoming reagent, if nucleophile attacks on methanol then it undergoes nucleophilic reaction and if electrophile attacks on methanol then it undergoes electrophilic reaction i.e Methanol reacts with both.... Student of A-level, XII, From Moro, SOMIA AKBAR MEMON
It can be defined as followed. special type of nucleophilic substitution.
A nucleophile attacks an electrophilic site and replaces a leaving group. e.g. OH- attacks R-Br to give R-OH.
A nucleophilic substitution reaction would take place, replacing various numbers of chlorine atoms with iodine atoms. Thus a mixture of compounds is produced.

The nucleophilic oxygen in the alcohol can attack the carbonyl carbon of the aldehyde to form an ester. This reaction can be carried out under acidic conditions.
The Nucleophilic substitution of Halo alkanes
The question is probably intended to be about SN1 reaction. See the following from Wikipedia, accessed Feb. 25, 2013: "The SN1 reaction is a substitution reaction in organic chemistry. "SN" stands for nucleophilic substitution and the "1" represents the fact that the rate-determining step is unimolecular".

i think the question is wrong.benzene doesn't respond nucleophilic substitution respond electrophilic substitution it is electrophilic then due to resonance there is a partial double bond between carbon of benzene and halogens.so halobenzenes are chemically inert towards electrophilic substitution.

1,2-addition occurs when the carbonyl oxygen (1) is attached by the electrophile and the carbonyl carbon (2) attaches to the nucleophile for the 1,4 the 4 is the beta carbon
It is for Substitution Nucleophilic reaction in organic molecules.
