Draw a structural formula of the SR configuration of the compound shown below. OH (R • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • Include H atoms at chiral centers only. • If a group is achiral, do not use wedged or hashed bonds on it.

2 Circle and name all functional groups in the polyfunctional molecule shown. This molecule is commonly known as Safrole. It can be extracted from the sassafras plant and added into many oils to give a "sweet shop" aroma. In addition, it can be used to help create natural insecticides. What functional group on this molecule is likely to produce the smell associated with Safrole?

One of the ingredients in the Pfizer-BioNTech (mRNA) vaccine is shown below: но. N'

List the name and position for each substituent in this organic molecule on a separate row of the table below: CH3 Q-CH₂-CH3 CH3–CH–CH2–CH-CH=CH2–CH2–CH3 CH₂-CH₂-CH3 Your answer for the name column should be just one word. In the position column, write the number of the carbon where the substituent is attached to the parent chain (which has been highlighted for you). Note for advanced students: You may assume that the parent chain is numbered from left-to-right in this molecule. You can add more rows to the table if you need them. name Add Row position 0 X

Each molecule below contains three functional groups. Identify them.Refer to your functional group handout if needed.The functional groups with the C=O bond can be tricky.
