Homework Answers
6. iodine is the best leaving group because it leaves the molecule with a negative charge and iodine with its large size can accomodate the negative charge in a better way in comparison to other halogens.
7. CN will react faster in SN2 mechanism because it has a negative charge on carbon which makes it more nucleophilic in comparison to NH3 which has a lone pair electrons

5) Iodine is a better leaving group than bromine. But iodine is
a better nucleophile than bromine. Why is that?
Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the...

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.
b. Why is...

7. Which of the following statements is (are) true about a reaction that follows an Sul mechanism? A. The reaction is fastest with primary alkyl halides. B. The reaction exhibits a one-step mechanism. C. The reaction rate increases as the leaving group ability increases. D. The reaction rate increases as the strength of the nucleophile increases. E. Statements (The reaction rate increases as the leaving group ability increases) and (The reaction rate increases as the strength of the nucleophile increases)...
