(c) Imagine that you are working for a chemical company and it was your job to perform a similar reaction to the
one above, with the exception of the S atom in this reaction being replaced by an O atom. During the reaction, you
observe the formation of three separate molecules instead of the single molecule obtained above. What is the likeliest
other products that are formed? Draw them in the box provided.
3. For the reactions below, draw the arrows corresponding to the transformations and draw in the boxes the reactants
or products as indicated. Note: Part A should have arrows drawn going from the reactants to the middle structure
and the arrows on the middle structure that would yield the final structure. For part B, you will need to draw in
the reactant before being able to draw the arrows corresponding to product formation.
