1. Using the values from the helium emission spectrum, generate a calibration curve on Microsoft Excel or other graphing software. If you are new to Microsoft Excel, specific instructions (with pictures) are given at the end of this lab and will be discussed in lab. a) In Excel, create a column labeled "scale position." This will serve as your x-values. Create another column labeled "wavelength." This will serve as your y-values. b) Enter the values for your scale position and wavelengths into each column. Do not put unit labels with the numbers. c) Create four separate graphs, one each for the four required types of trendlines ("linear", "logarithmic", "exponential", and "polynomial"). Each graph will have the same data plotted but have a different trendline. See the "Curve Fitting Using an Excel Spreadsheet" section at the end of this write-up for additional information about how to make these graphs. i.

Total number of stereoisomers possible for the following compounds is HINT: a. 4 How many possible stereoisomers? How do we know how many stereoisomers are possible for a given structure? There is actually a straightforward way to figure this out. All we need to do is count the number of chiral centers and stereogenic alkene groups, the use this following rule: number of stereoisomeric forms = 2" ... where n = the number of chiral centers plus the number of stereogenic alkene groups b. 2 Consider for example a molecule with two chiral centers and one stereogenic alkene. By the rule stated above, we know right away that there must be eight possible stereoisomers. terminal alkene OH stereogenic alkene C. 8 OH d. 3 OH chiral center HO OH 3 2 = 8 T nonstereogenic alkenes (cannot be labelled E or Z) ←
