Chlorofluorocarbons (CFCs) used to be produced in mass quantities owing to their use as stable organic compounds in a variety of applications. However, the Montreal Protocol (established in 1997) prohibited their use because they were shown to be responsible for ozone layer depletion You have isolated a compound (CFC1) that you suspect is a chlorofluorocarbon. Using the NMR predict it's structure (10 marks). In addition, provide the structure of a derivative (A or B; can be made in 1 step from CFC1) (10 marks), and the synthesis of A or B staring from benzene (10 marks) Spectral data of the compounds is given below. Bonus marks will be awarded for correctly identifying the structure of the remaining derivative (10 bonus marks) 10 marks +10 bonus) 10 marks 10 marks A Formula CFC1 Formula: and any other Diagnostic IR peaks nothing obvious H-NMR of CFC1 C7H6CIF 52 7 5 4 PPM H-NMR of Derivative A Chemcal Formula: C7HsCIFNO2 12 Diagnostic IR peaks- nothing [1 9 1H-NMR of Derivative B Chemical Formula: CHsFO2 Diagnostic IR peaks 1725 & 3000 (broad) cm1 1 2 1 0 8
