(a) Interpretation: We need to change the given digits to two significant figures by round off or by addition of zero. Concept Introduction: To change the significant figure as given we can round off the number or we can add zeros to the number. To round off any number we have to follow some rules. In a number ended with 5, 6, 7, 8, or 9 must be rounded to next nearest 0 digit number. In a number followed by 0, 1, 2, 3, or 4 must be rounded the number down. If we have decimals; in rounding off numbers we have to keep the last figure unchanged and the first figure dropped is less than 5 whereas more than 5 will change the number to the next number.

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.
