Nucleophilic substitution occurs when a nucleophile (some species with an affinity for positive charge) attacks an atom that is electron rich (electrophile). The atom under attack cannot form additional bonds so must release a bond to another atom or side group that has less affinity for it. This often happens simultaneously in an SN2 type reaction but can also occur in the slower 2 step SN1 reaction. Now the nucleophile has taken the place of (substituted itself for) the atom or group with less affinity.

Is Williamson's synthesis an example of nucleophilic substitution rxn?
Williamson's synthesis an example of nucleophilic substitution rxn, in this rxn an alkyl halide is allowed to react with a Na alkokide.
What are nucleophilic reaction?
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.
Why does a high temperature favor a nucleophilic elimination over nucleophilic substitution?
My guess would be that Elimination reactions are much higher energy, as it breaks bonds. Higher temperature = higher energy.
What is ammonolysis?
It can be defined as followed. special type of nucleophilic substitution.
What is nucleophilic substitution reaction?
A nucleophile attacks an electrophilic site and replaces a leaving group. e.g. OH- attacks R-Br to give R-OH.

Why halobenzenes are less reactive towards nucleophilic substitution reaction?
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.
How do you write the nucleophilic substitution reactions for aniline and toluene?
aniline would go through an electrophilic substitution, it is a weak base

What has the author Keith Graham Barnett written?
Keith Graham Barnett has written: 'Novel nucleophilic substitution reactions of p-Phenetidine derivatives'
What is the equation for the reaction involved when the bromine is mixed with the ethyne?
The Nucleophilic substitution of Halo alkanes
Why aryl halides gives nucleophilic substitution very slowly?
The lone pair of electron present on the halogen atom overlaps with the adjacent pi bond electrons of the benzene ring and get delocalised. As a result of this the carbon-halogen bond strength increases and halogen atom can't be displaced easily.
What is ammonolysis?
It can be defined as followed. special type of nucleophilic substitution.

What will iodine do when it is put in trichloromethane?
A nucleophilic substitution reaction would take place, replacing various numbers of chlorine atoms with iodine atoms. Thus a mixture of compounds is produced.
What is SNi reaction?
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".
