A nucleophile attacks an electrophilic site and replaces a leaving group. e.g. OH- attacks R-Br to give R-OH.
No, Williamson's synthesis is an example of an SN2 (bimolecular nucleophilic substitution) reaction, not nucleophilic substitution. In this reaction, an alkyl halide reacts with a strong nucleophile to form an ether by substitution of the halogen atom.
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.
Haloalkenes are more reactive towards nucleophilic substitution reactions because the presence of the electron-withdrawing halogen creates partial positive charge on the carbon, making it more prone to attack by nucleophiles. Additionally, the double bond in haloalkenes provides a site for nucleophilic attack, increasing the rate of reaction.
The nucleophilic substitution reaction occurs at position 2 in pyridine because it is the most sterically accessible site due to the presence of the nitrogen lone pair at that position. The aromaticity of the pyridine ring also plays a role in stabilizing the intermediate formed during the substitution reaction at this position.
In an SN1 nucleophilic substitution reaction, the mechanism involves a two-step process. First, the leaving group leaves the substrate, forming a carbocation intermediate. Then, the nucleophile attacks the carbocation, leading to the formation of the substitution product. This reaction is characterized by the formation of a carbocation intermediate and is favored in polar protic solvents.

The reaction is a nucleophilic substitution reaction. In this case, 1-bromopropane undergoes a substitution reaction with a hydroxide ion (OH-) to form propan-1-ol through the displacement of the bromine atom by the hydroxyl group.
Electrophilic reagents are chemical species which in the course of chemical reactions, acquire electrons or a share in electrons from other molecules or ions. Nucleophilic reagents do the opposite of electrophilic reagents.
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".
The factors that influence the reactivities of alkyl halides in nucleophilic substitution reactions include the nature of the alkyl group, the type of halogen, the solvent used, and the strength of the nucleophile. These factors can affect the rate and outcome of the reaction.
The reaction between bromocyclopentane and methoxide will result in the substitution of bromine with the methoxy group, forming methoxycyclopentane as the product. This is a nucleophilic substitution reaction.
Furan does not typically undergo nucleophilic substitution reactions because of its aromatic nature, which offers stability due to delocalization of the pi electrons in the ring. This makes furan less reactive towards nucleophilic attack compared to non-aromatic compounds.
