Synthesize each compound from acetylene. You may use any other organic or inorganic reagents. a.
How would you carry out the synthesis below? Additional
carbons may come from any alkyl halide with 3 C's or less. Show the
reagents needed for each step of your transformation, but do NOT
draw the mechanisms for each step.

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...

"Carboxylic acids can be made by the hydrolysis of nitriles,
which in turn can be made from an alkyl halide. Draw the structures
of a starting alkyl bromide and the intermediate nitrile that would
be used in the synthesis of 3-methylbutanoic acid (also known as
isovaleric acid). Do not show free ions."
I answered the first part right but it is saying that the
second part is incorrect. On my carbon that is triple bonded to the
nitrogen has a...

Alkyl halides may undergo elimination reactions with BrØnstead-Lowry bases in which the halide and an adjacent proton are lost to form a new π bond. Because of the loss of a proton and a halide anion the reactions are termed ‘dehydrohalogenation’. The two most common associated mechanisms are designated as either unimolecular (E1) or bimolecular (E2) elimination reactions based on reaction rate studies. E1 reactions proceed via a two-step mechanism that involves the cleavage of the leaving group (here the...
