as order of reactivity of sn1 reaction is 3>2>1 , we do not synthesise primary alkyl halide using sn1 reation. as there is no pushing from other carbon atoms, it is difficult for the X part of RX to separate itself.

in sn1 reaction the electrophile leaves the substrate forming a carboncation.afterwards the nucleophile while attack the carboncation and usually recimes may be formed in sn1 reaction depending on whether the carboncation experienced a front of backside attack. in sn2 reaction the departing and attacking proccess occurs at the same time. these is pule rampai from the university of johannesburg
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".
Has to be a simple SN1 reaction. tertiary carbocation, very very stable due to three phenyl groups and very bulky.

An SN1 reaction is an unimolecular substitution reaction (hence the name SN1). This means it's a substitution reaction in which the rate of the reaction is only dependent on the concentration of the substrate, as opposed to SN2. In an SN1 reaction, the leaving group of the substrate departs first, leaving a carbocation on the substrate. Then, the nucleophile donates an electron pair to the carbocation and forms a bond. In an SN1 reaction, the carbon molecule bonded to the leaving group must therefore be a tertiary substituted carbon. This is because when the leaving group departs from the molecule, only a tertiary substituted carbon is stable enough as a cation. Keep in mind that an SN1 reaction leads to two isomer products. If the tertiary carbon is a chiral senter, the two products of the SN1 reaction have an R and S configuration, respectively. The mixture of these isomers is racemic, and the isomers have identical physical properties.

Fluorine gas, the element, is more reactive than the elemental gas chlorine. The ions fluoride and chloride the reactivity depends on the solvents and the reaction mechanism. sn1 vs. sn2.

If you look at the structure of 2-methyl-2-propanol, you can see that the carbon attached to the alcohol (OH) is a tertiary carbon, attached to 3 other carbons. Because butanol isomers react with an SN1 mechanism, the more complex compounds react faster. In an SN1, the tertiary reacts before the secondary reacts before the primary. Hope this helps some!

The neighboring group effect refers to the influence that a functional group or substituent has on the reactivity of a nearby functional group in a molecule. This can include both intramolecular interactions that affect the outcome of chemical reactions, as well as changes in the stability or reactivity of a functional group due to the presence of neighboring groups.
