HW1. Solid methyl cinnamate is (basic/ acidic/ neutral)?
Solid trans-cinnamic acid is (basic/ acidic/ neutral)?
If you could not perform an FT-IR, GC-MS, or H¹ NMR, what two things could you do in the lab
to validate the presence of the product upon isolation given that both the starting material and
product are white solids?
1.
2.
HW2. A wash removes undesired materials from the phase the product is in to another phase.
An extraction removes the desired product from one phase to another phase. So moving an
unwanted material out of a phase is a wash and moving a desired material out of a phase is an
extraction.
Complete the following sentences:
a. The first use of 3 x 15 mL of diethyl ether (expt. step 7) was labeled a wash because:
b. If in step 8, your desired product did not crash out of solution but remained in the
aqueous layer you would have needed to use 3 x 15 mL of diethyl ether to perform an
extraction because:
HW3. (If both Wittig and Saponification Labs were performed) What was the overall yield of
Show your work
making trans-cinnamic acid starting from benzaldehyde (2 steps)?
below:
