- 6. Use the molecule below to answer the following questions. a) Name the following molecule. b) Why is it necessary to provide R or S designation in order to clearly communicate molecular structure for this molecule? c) How many stereoisomers of this molecule are possible? Which of them are enantiomers to each other? Which are diastereomers? SH ICNIndicate whether the pair of structures shown represent stereoisomers, constitutional isomers, different conformations of the same compound, or the same conformation of a compound view from a different perspective. Note that cis, trans isomers are an example of stereoisomers. Br H3C- Br Br OCH3 H3C Br OCH3 stereoisomers constitutional isomers different conformations same conformation.Based on the structures of lycopene and β-carotene, which are two chemicals found in another common vegetable, the tomato, answer the following questions: 1. Are they stereoisomers, constitutional isomers or not even isomers? 2. Do you expect them to be relatively polar or nonpolar substances? Why? 3. How many double bonds are in lycopene? How many in β -carotene? 4. As lycopene is transformed into β -carotene, how many pi electrons from the double bonds are transformed into single bonds? How many new single bonds are being formed in β -carotene? 5. The first step of a possible mechanism for the ring closure in the transformation is outlined below (only part of the structure is shown for simplicity). Draw the product that results from this arrow pushing mechanism. Be sure to include any formal charges that arise from the carbon atoms.
