Make a table of physical contents for S Limonene and R Carvone Include: structures, formula, molecular...
Write bond line structures, with dashed and wedged lines, of (-)-carvone, (+)-carvone, (-)limonene and (+)-limonene. Assign the absolute configuration (R, S) of the chiral center in each compound.
After your procedure, draw all FOUR of the following structures in your pre-lab report. Make sure you clearly label the stereogenic center, the priority of each group around the stereogenic center, and then label the chiral centers with R or S. H Figure 2-3a.

A compound with the molecular formula of C7H16 has the following physical properties: mp= -123.8 C; bp= 79.2 C; density = 0.6739 g/mL. There are several compounds with that formula. Use a reference book to determine the name and the structural formula of the isomer with those specific properties. Hint: Use the boiling point index at the end of the section “Physical Constants of Organic Compounds” in the CRC Handbook of Chemistry and Physics. Determine the boiling point, water solubility...
