Below are pictures of my HNMR and CNMR for salenH2. I have already assigned some of the protons and carbons myself, but I am having trouble with the rest. As far as I know, there are 8 unique carbons and 7 unique hydrogens. The carbons are numbered and the hydrogens are lettered. I have included a labeled picture of the compound on each page.

correct answer? What information can be obtained from the Figure below? 14 12 10 pH 8 6 4 20 volume (mL) O The equivalence point occurs at pOH = 10 and the pKb = 6.0 O Both the pOH and the pKb cannot be calculated from the graph. The equivalence point occurs at pH = 8.0 and the pka = 4.0 O The equivalence point occurs at pH = 7.0 but the pka is not known from the graph.
