15 pts total
1. Consider the following condensed molecular structure. For each structure, convert the
condensed structure into a correct bond - line or wedge - dash structure, as appropriate (3 pts):
a. CH3CH(OCH3)CHCHCH2CCC(O)CH3
2. Consider the following molecule, a derivative of
the amino acid threonine. (6 pts):
a. What is the molecular formula of this
molecule? (1pt)
b. Using the above structure, label the hybridization and shape for at least 4 non-hydrogen
atoms. Ensure that you label & identify at least one atom from each type of
hybridization. (2 pts)
c. Briefly explain what it means for an atom to be hybridized (3 pts)

  1. Consider the following Acid – Base reactions. Show how the Acid – Base reactions occur using the arrow pushing formalism in order to predict the structure of the products. Ensure that all structures are drawn using either bond-line or wedge-dash representations. Appropriately identify each molecule as part of this acid –base reaction. (6 pts = 3 pts each)

a. HI + CH 3 OCH 3

b. CH 3 COOH + (CH 3 ) 2 CHONa

Extra credit: (3 pts) Only do if you are finished with the quiz in the allotted 20 minutes

Using the arrow-pushing formalism, predict how the following non-acid/base reaction might occur; include a bond-line drawing of all structures.
