(a) Interpretation: The element having the smaller molar mass needs to be determined. Concept introduction: The number of moles of an atom of element is related to mass and molar mass as follows: n = m M Here, m is mass of atom of element in grams and M is molar mass in grams/mol. In 1 mol of an element the number of atoms is 6.023 × 10 23 and mass of 1 mol of an element is molar mass thus, mass of 6.023 × 10 23 of element is molar mass.

What spectral features allow you to differentiate the product from the starting material?
Use four separate paragraphs for each set of comparisons. You should have one paragraph each devoted to MS, HNMR, CNMR and IR.
2) For MS, the differing masses of molecular ions are a popular starting point. Including a unique fragmentation is important, too.
3) For HNMR, CNMR and IR state the peaks that are different and what makes them different (usually the presence or absence of certain groups). See if you can find two differences (in each set of IR, HNMR and CNMR spectra) due to the presence or absence of a functional group. Include peak locations. Alternatively, you can state a shift of a peak due to a change near a given functional group. Including peak locations for shifted peaks, as well as what these peaks are due to. Ideally, your focus should be on not just identifying the differences but explaining them in terms of functional group changes.
