Biomass (CH1.8O0.5 N 0.5) can be converted to glycerol by anerobic (in the absence of air) reaction with ammonia and glucose. In one batch of reactants, 52.4 L of CO2 measured at 300 K and 95 kPa was obtained per mole of glucose in the reactor. The molar stoichiometric ratio of nitrogen produced to ammonia reacted in the reaction equation is one to one, and the mol CO2/mol C6H12O6 = 2. How much (in g mol) (a) glycerol was produced and (b) how much biomass reacted to produce the 52.4 L of CO2?
Label and identify ALL functional groups. Label the chiral carbons (*), label the priorities (1,2,3,4) of the four "things" connected to the chiral carbon, draw the arrow or rotation and identify as R or S.
