Description

1. Classify the compounds as constitutional isomers, stereoisomers, or identical.

2. Identify if the following molecules are chiral or achiral. If they are chiral, identify the chiral center. If they are achiral, draw the plane of symmetry.

3. We previously saw vincristine on our week 3 worksheet. Circle all of its chiral centers.

4. Identify which stereoisomers are enantiomers and which are diastereomers. Identify if each stereogenic center is either S or R.

5. The structure of tartaric acid is shown below. Circle the stereocenters. What is the maximum number of stereoisomers possible for this compound? Draw a structure of the meso isomer, showing necessary stereochemistry.

6. Identify the structures as either enantiomers, meso compounds, diastereomers, or identical.

7. Identify the stereocenters for the following molecule and label them as R or S. Explain the difference of melting point.

mp = 40-41 °C

mp = 117-118 °C

mp = 117-118 °C...
