Calculate the Index of Hydrogen Deficiency (IHD; also known as degree of unsaturation) for the following molecular formulas and place your response in the designated box. Then answer part (d). a. \( \mathrm{C}_{8} \mathrm{H}_{10} \mathrm{O}_{3} \) b. \( \mathrm{C}_{10} \mathrm{H}_{15} \mathrm{Cl}_{3} \mathrm{O}_{2} \) a. \( \mathrm{IHD}= \) b. \( I H D= \) c. \( \mathrm{C}_{7} \mathrm{H}_{5} \mathrm{~N} \) c. \( \mathrm{IHD}= \) d. Propose two different combinations of bonding features to account for an IHD of 5 in a molecule consisting of \( \mathrm{C} \) and \( \mathrm{H} \) atoms and one \( \mathrm{O} \) atom only (i.e. \( \mathrm{C}_{\mathrm{x}} \mathrm{H}_{y} \mathrm{O} \) ). For example, a molecule with molecular formula \( \mathrm{C}_{\mathrm{x}} \mathrm{H}_{\mathrm{y}} \mathrm{O} \) and \( \mathrm{IHD}=2 \) may have one \( \mathrm{C}=\mathrm{O} \) bond and one ring (this is an example of one combination). For this exercise, do not propose more than one ring. 2. How many sets of structurally different hydrogens (how many different types or how many signals would you expect to see in the corresponding ' \( \mathrm{H} \)-NMR spectrum) are present in the following molecules? Place your numerical answer in the box below each structure. Ibuprofen Melatonin
