Question 4 10 points Save Answ A an unknown molecule has the chemical formula C9H13N. Based on the chemical formula, the hydrogen deficiency index is (a small whole number). Catalytic hydrogenation of the substance yields a molecule whose chemical formula is CH17 Thus we can conclude that the original molecule had number of pi-bonds and number of rings. Ozonolysis of the molecule yields The following Based on all of this, one possible structure for the molecule is (type in number...

1. Index of hydrogen deficiency (IHD)/ degree of unsaturation will tell us the total number of rings and pi bonds in a molecule. Although the final structure can only be verified by IR/NMR spectra, if molecular formula is known, 1HD may be calculated and this will aive us an initial hint about the structure of an unknown molecule. HD is given by following equation: 2C + 2-H +N-X # carbons, H = # hydrogens, IHD = where, C N= #Nitrogens...
