The conversion of alcohols into alkyl halides by reaction with hydrogen halides is an example of a Nucleophilic Substitution Reaction. This kind of reaction can proceed by two different mechanisms depending on the structure of alcohol substrates used. Generally, primary alcohols are substituted via SN2 mechanism, while secondary and tertiary alcohols undergo SN1 mechanism.
Consider the following reaction given in the picture below and the questions in the picture too.
Write a reaction that could be carried out to synthesize 1-(4-methylphenyl)ethanol (reactants will be a combination of Grignard reagent and carbonyl compound).
[Review Topics]
[References]
Acyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the
tetrahedral intermediate as it is first formed in the following reaction.
H3C
CH3
H2O
NaOH
