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...

1) State which of the electrophiles given below will react
preferentially by i) SN1, ii) by SN2, or iii) capable of reacting
by either of the two mechanisms depending on the given conditions.
How can you affect those conditions to favour SN1 or SN2? Reason
your predictions based on the structures of the compounds. Br-CH3,
