STEP 1: IDENTIFY A COMPOUND
The goal of this assignment is to help you make connections among concepts that w are learning in class and topics that you are interested. This could be something you are learning in another class or something you read about. Feel free to select any compound you wish as long as your compound contains at least 3 chiral carbons. Many medications contain multiple chiral carbons. Your molecule from Extension 1 may even have at least 3 chiral carbons. The only criteria is that these compounds are not featured in our textbook or learning materials for chapter 5.
If you are having trouble identifying a compound, search for the structural formulas for the following:
Carbohydrates including hexoses, heptoses (many of the pentoses are in the textbook)
Pestices, such as some of the pyrethroids
Statins (cholesterol medications)
Steriods, hormones, and anibolic steriodsSTEP 2: ID KEY INFORMATIONUse the power of the internet to identify the name, molecular formula, and CAS number (if available) for your compound of interest.Some resources to get your started:
ChemID Plus (NIH):
NIST Chemistry WebBook:
Step 3: check if someone else selected the compound, I have attached a picture of the compounds that are already selected.
Step 4: let me know what compound you selected before you start.
Step5: complete the assignment.
This will require several drawings that are labeled.
These drawings should be pasted into the document, NOT submitted separately as pictures.
All drawings are to be computer generated (You can use any application you wish. :
). There are two ways to include images into the doc.
Print out your drawings and label them by hand. Make sure that you have a CLEAR image to incorporate in the final doc.
Label them in the drawing program using the text feature.
All formulas submitted should use solid and dashed wedges to indicate 3D
TOTAL number of chiral carbons
Highlight in the name where the
chiral carbons are designated.
How manys R stereocenters are
designated in the name?
How manys S stereocenters are
designated in the name?
How many diastereomers are
possible for this compound?
Insert a labeled bond-line formula of the compound.
ONE paragraph describing the compound. This paragraph should include at least three chemical facts about
the compound (i.e. chemical property, physical property, applications/uses of the compound); no history,
prescription information, etc. This paragraph should be spell checked, use proper punctuation and grammar,
and be college level work. The voice used should be 3rd person. Citations given for information sources using
either APA or MLA format.
Functional groups present:
Insert a labeled bond-line formula of the compound with all functional groups clearly labeled. The formula
submitted should use solid and dashed wedges to indicate 3D arrangement.
Identify ALL chiral carbons present:
Insert a labeled bond-line formula of the compound with all chiral carbons highlighted and labeled as R or S.
● If double bonds are present, label all double bonds as E or Z.
Insert a bond-line formula the enantiomer of the compound. Highlight the chiral carbons and label them as R or
Insert a bond-line formula of TWO diastereomers of the compound. Highlight the chiral carbons and label them
as R or S.
