Question

2. What laboratory technique might be useful for determining the molecular weight of the tan solid you made and therefore the success of the experiment? Hint: you have never used it and we don't have this instrument, but it was described in an earlier experiment.) of the ve this instrument, but it weas ofthe epment 3. Why does this reaction only form a dimer, rather than continuing on to a trimer, tetramer, etc.? Keep in mind the following water solubilities: vanillin 0.01 g/mL, divanillin estimated 0.003 g/mL

Explanation / Answer

2) A mass spectrometer can be used to accurately measure the molecular weight of the target molecule.

3) It is quite likely that the divanillin formed would precipiate out thereby inhibiting the formation of trimers and tetramers.
