7. Using 'H NMR to determine the structure of a molecule, C,H10Cl2. Use the IHD formula to determine how many rings and or pi bonds in the molecule. (hint: if IHD 4 or more it suggests there is a benzene ring. That would be consistent with the fact that there are signals in the aromatic region.(1) Given your IHD value and the signals around 7 ppm on the NMR spectrum what familiar functional group must be a part of your molecule? 0.75 Determine how many neighbors each type of hydrogen a-e has using the n+1 rule. 1.25 a b d e e b 2H 3H d singlet 2H 2H triplet a triplet sextet 1H singlet 7 5 3 2 PPM From the information you have derived and the provided data, determine the structure of the molecule.
