Describe procedures for preparing each of the following compounds, using ethanol as the source for all of their carbon atoms (you can use any reagent you like, but every carbon in every product below must have originated in ethanol; once you prepare a compound, you need not repeat its synthesis in a subsequent part of this problem):
a. ethylamine
b. N-ethylacetamide (CH3CH2NHCOCH3)
c. diethylamine (make sure to use a RELIABLE method)
d. tetraethylammonium iodide
e. CH3CH2N=CH2CH3 (this compound is a Schiff Base)
Calculate the vapor pressure of a solution made by dissolving 109 grams of glucose
A compound, C10H14, shows an IR peak at 745 cm-1. Its 1H NMR spectrum has peaks at delta 7.18 (4 H, broad singlet), 2.70 (4 H, quartet, J=7 Hz), and 1.20 (6 H, triplet, J=7 Hz).
