1) Draw the arrows to show bond formation and breaking for the following mechanisms and complete questions b, c, and d. Marking scheme is also provided. (9 marks total) a) All tails of arrows must start at electrons. The arrows must start in the middle of a sigma bond or at a lone pair (2 marks) Take % mark for each mistake until you reach zero. All heads of arrows must end at an atom. (2 marks) Take X mark...
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...
4) Can you ever have only SN2 or only SN1? 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 leaving group departs with both electrons of its bond to...

Given that the SN2 mechanism requires the nucleophile to force out the leaving group, what would you expect the product ratio of alkyl bromide to alky chloride be when sulfuric acid is the solvent? Also given that the SN1 mechanism requires the nucleophile to react with an empty p orbital of a carbocation involving bond formation, what would you expect the product ratio of alkyl bromide to alky chloride be when sulfuric acid is the solvent? R-Br > R-Cl or...
