2) Rank the nucleophiles given below based on high, mediocre,
and low nucleophilicity and reason why based on their structures.
HO-CH3, H2N-CH3, KO-CH3, KO-C(CH3)3
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...
