3) Name two solvents that are commonly used for SN2 reactions.
because they considerably slow down SN1 reactions.
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...

Name: 2.2 Hydrogen The relative isotopic abundance for hydrogen 2H: 1H is about 0.00016: 1, and therefore hydrogen isotopic substitutions are unlikely to play a major role in any observed (M+1) peak. The isotope 2H is called "heavy hydrogen or deuterium, and is given the symbol D. We can often provide support for mechanisms by incorporating isotopes such as 13C or D into compounds using isotopically labelled reagents. Mass spectrometry is a useful tool for analyzing such isotopic incorporation by...
