3. Draw the two chair conformers of each molecule shown below. Circle the more stable conformer. If both conformers are equally as stable, write "equal" instead. a b с

Compare the following conformers of 1-fluoropropan-1-ol. Match each conformer to their corresponding relative energy. Recall, the more stable the conformer the lower the energy. OH CH3 'F 2. HOH 2nd Highest Energy H 2nd Lowest Energy H3C 3. H. ОН Lowest Energy H 'F Highest Energy ČH3 4. H3C, OH 'F 1. >

4. Clearly draw both Chair Conformations. of the following molecule Xordin 5. for the Molecule in Question 4 - Circle the lowest energy Chair Conformat. TAM!

6. Draw the two chair conformations of the molecule below. Which is the most stable? HO.

Consider 1,2-dimethylcyclohexane.Q: Draw the two possible chair conformations for the cis isomer. Which conformation, if either, is more stable?

Q6. Draw both chair conformations for the following compound (Carbons atoms are numbered in the chair structures for your convenience. Idențify the more stable conformation.

For every structure below, draw the most stable chair conformation. Where two or more conformations are equally stable, draw both.

2. H3CO H3CO HO 1. Consider the molecule shown below. [1] Draw the two chair conformations for the compound. [2] Identify which of the two chair conformations is more stable and explain why. H3CO Jonoto NH₂ How are the following molecules related? (exactly the same, completely different, constitutional isomers, enantiomers, or diastereomers). OH OH OCH3 HO“ OH H3CO H3CO is content is protected and may not be shared, uploaded of ributed OCH3 HO,,, OH O... "OCH3

5. For the pair of compounds circle the compound which is more stable (you may find it helpful to draw out the chair conformation)

7. For each of these, draw the two conformers by adding the missing methyl and ethyl group. The second one should be the ring flip of the first. Identify which is more stable. As we learned, the larger group prefers the equatorial position. Me ring Et flip ring Me. Et flip ring Et flip Me
