A non-branching ether has a molecular ion peak at m/z=102 and another significant peak at m/z=57. Draw the structure of the molecule. You do not need to show the hydrogen atoms, but you may want to place the carbon atoms in a zigzag pattern to make it easier to count how many you've drawn.

a) Describe the difference between the base peak and the parent
ion (or molecular ion) peak.
b) Identify the base peak and the parent ion (or molecular ion)
peak (if any) according to the mass spectrum.
c) Identify the mass fragments which correspond to m/z = 77,
105, 111, and 139.
d) Identify and give explanations for the magnitude (or
intensity) of the peaks at m/z = 113, 141, and 218.

charge)
label the molecular ion peak as "M+" (if present)
label major peaks other than the molecular ion with three
things:
1) the mass to charge ratio
2) the structure or formula for that charged fragment
3) another formula to show which fragment was lost by the molecular
ion to form that ion

Some tert-butyl ether is formed in the solvolysis of tert-butyl chloride. Where does this product come from (i.e. what is the substrate and what is the nucleophile?) Do you think this will affect the kinetics of the reaction? Think about the rate-limiting step in the reaction.
