one 1o alcohol, one 2o alcohol, one 3o alcohol, one 1o amine, one 2o amine, one 3o amine and
2. The mass spectrum below corresponds to C7H7X: benzyliodide, benzylbromide, benzylchloride or benzylfluoride.
i. Calculate the degree of unsaturation for these compounds.
ii. Based on your analysis of the mass spectrum, what is the molecular formula and structure
of the compound? Give the reason for your answer using data from the spectrum below. In

1. Reference: http://www.mcld.co.uk/hiv/?q=lopinavir
Lopinavir is an antiretroviral developed by Abbott to treat HIV/AIDS and is administered as a coformulation with an earlier Abbott drug, Ritanovir (this helps bioavailablity).
i. Degree of Unsaturation = [2 + (2 x #Carbons) + #Nitrogens - #Hydrogens - #Halogens]/2
= [2 + (2 x 7) + 0 - 7 - 1]/2
The dominant molecular ion corresponds to 126 m/z which is the calculated molecular mass for this compound. The other major signal at 91 m/z ...
