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.
[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

The reaction that occurs when the benzaldehyde you have is reacted in a basic environment is called the Cannizzaro reaction, and when it is reacted with cyanide, it is called benzoin production. Write down the reaction mechanisms of these reactions and explain why.
