The amount of tritium left after a period of 61.5 years is to be determined. Concept Introduction: The half-life is the time required for the decay of one-half of a radioactive nuclide into a different nuclide. The half-life of a nuclide always remains same irrespective of the amount of nuclide, temperature, or any other conditions.

Interpreting NMR spectra is a skill that often requires some amount of practice, which, in turn, necessitates access to a collection of NMR spectra. Beyond Labz Organic Synthesis and Organic Qualitative Analysis have spectral libraries containing over 700 1H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish to select other compounds for additional practice. 1. Write the IUPAC names for the following two structures: Question 2 Question 3 2.
