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...
