I have a question about nucleophile concentration and the dilution process. Why does 25:75 mix - .25 mL 18% solution of sodium iodide in acetone and .75mL of acetone have a faster reaction rate for 1-bromobutane than 1 mL 18% solution of sodium iodide in acetone ? I would appreciate it
Homework Answers
The reaction proceeds through Sn2 mechanism. The Sn2 reaction is favourable in polar aprotic solvent.
Acetone is a polar aprotic solvent. In 0.25 ml 18% sodium iodide + 0.75 ml of acetone has higher amount of acetone than in 1 ml of 18% NaI in acetone.
Higher amount of acetone dissolves the nucleophile better and hence the reaction is faster for the 1st case.

1. In both the sodium iodide
test and the silver nitrate test, why does 2-bromobutane react
faster than 2-chlorobutane?
Bromine is a better leaving group since it is a weaker base than
chlorine is.
2. a. Why does benzyl chloride react under both
SN1 and SN2 conditions?
Benzyl
chloride is a primary alkyl halide, hence reactive under SN2
conditions.
The
primary carbocation formed due to the departure of Cl- is
stabilized by the pi electrons in the benzene ring.

Please help. Due to corona, this is a theoretical lab and I am
very confused.

Please give detailed answers to the pre and post lab questions.
Thank you!
NUCLEOPHILIC DISPLACEMENT- FORMATION OF AN ETHER BY AN SN2 REACTION Bond formation by use of an SN2 reaction is very important for organic and biological synthesis. Many new bonds formed make use of this versatile reaction pathway. In this reaction, one partner is the nucleophile and the other partner is the electrophile. The electrophile will have a leaving group that will be lost in the reaction. In...

2. Why doesn’t sodium acetate act as soap?
Sodium acetate cannot be used as soap because there is no
non-polar hydrocarbon side component long enough to bind nonpolar
dirt fats or oils. Without this organic component it cannot be used
as soap.???

I need to: DETERMINE THE CONCENTRATION OF HYDROGEN PEROXIDE IN THE SOLUTION how ?? THEORY Titrimetry, or titrimetric analysis, is an example of a so-called classical method of analysis. Titrimetry is a convenient method of getting very small amounts of chemicals in to a reaction because the method involves the use of dilute solutions of reactants. Hydrogen peroxide reacts with potassium iodide according to the reaction given below: HB2BOB2B + 2HP+P + 2IP-P = IB2B + 2HB2BO (equation...
