In the case of an SN1 reaction, the nucleophile does not become involved until
after the rate-determining step. Therefore, changing the nucleophile has no effect
on the rate of an SN1 reaction, although it may change the product of the reaction
...

Organic Chemistry: An Acid—Base Approach
A nucleophile is a species that donates electrons to carbon, as first introduced in
Chapter 2, Section 2.6. A nucleophile is any species that donates electrons to an
electron-deficient car- bon, forming a new bond to carbon. In the previous ...

11.5.9 Structure-Function Correlations with the Nucleophile The rates of SN2
reactions correlate well with relative nucleophilicities, because the nucleophile is
intimately involved in the rate-determining step. In SN1 reactions, the nucleophile

and nucleophile. 269 RY + rate = - d[RX] dt = )t[RX][Y: Because the nucleophile is
intimately involved in the rate-determining step, not only will the rate depend on
its concentration, but the nature of the nucleophile will be very important in ...

If a nucleophile but no acid or base is present, the reaction mechanism will begin
with the nucleophile attacking the electrophilic carbonyl carbon atom (make a
new bond between a nucleophile and an electrophile). The 11- bond of the ...

Chemical Structure and Reactivity: An Integrated Approach
In the second stage, the tosylate is reacted with sodium azide, resulting in the
azide nucleophile displacing the tosylate group. Finally, the azide is reduced
using LiAlH4 to give the amine. 11.7.3 The effect of the nucleophile In the SN1 ...

Advanced Organic Chemistry: Part A: Structure and Mechanisms
The optimum reactant from a steric point of view is CH3–X, because it provides
the minimum hindrance to approach of the nucleophile. Each replacement of
hydrogen by an alkyl group decreases the rate of reaction. As in the case of the ...

Organic Chemistry, part 2 of 3
In an SN1 reaction, the addition of the nucleophile to the sp3 hybridized carbon
takes place after the leaving group departs. Therefore, the nucleophile has no
effect on the rate of the reaction because the rate of addition of the nucleophile is
...

The line, leading from the right edge of the page to each electrophile and ending
in an arrowhead, represents the attack of some nucleophile upon that
electrophile, with the point of attack being the atom at which the arrowhead is
directed.
