Draw most stable chair form for the more stable stereoisomer for the molecule. All help is appreciated yclohexane Chair Practice 9. For each of the following do two things: A draw the most stable chair form for the more stable stereoisomer for the molecule B. identify whether the more stable stereoisomer is cis or trans. 7. 1-butyl-2-methylcyclohexane 8. 3-t-butyl-1-methylcyclohexane 9. 1,4-diethylcyclohexane C. For each of the following, do two things: A draw the most stable chair form over groups C...
Draw one chair conformation of cis-2-methylcyclohexanol and one chair conformation of trans-2-methylcyclohexanol. Which is more stable?
6. Build the cyclobutane ring and study the angle strain and torsional strain. Draw the structures to explain these factors. 7. The conformation of cyclobutane is slightly folded. Folding gives partial relief from the eclipsing of bonds, as shown in the Newman projection. Compare this actual structure with the hypothetical planar structure. Draw the relevant structures. 8. trans-1,2-Dimethylcyclobutane is more stable than cis-1,2-dimethylcyclobutane, but cis-1,3- dimethylcyclobutane is more stable than trans-1,3-dimethylcyclobutane. Use the molecular models to find the reasons for...
11. Build the chair and boat conformations and identify the most stable conformation. Identify the 1,3-diaxial interactions. 12. Draw the most stable conformation of (a) ethylcyclohexane (b) 3-isopropyl-1,1-dimethylcyclohexane (c) cis-1-tert-butyl-4-isopropylcyclohexane 13. Draw all possible conformations of 1,4-dimethylcyclohexane and identify the most stable conformation 14. (a) Draw both chair conformations of cis-1,2-dimethylcyclohexane, and determine which conformer is more stable. (b) Repeat for the trans isomer. (c) Predict which isomer (cis or trans) is more stable. 15. (a) Draw both chair conformations...
Which of the following isotopes would you expect to be stable?
Would you expect the crystal on the right to be more or less stable enthalpically (AH)? A. Less stable B. More stable C. Equal AH Ostwald ripening Nature Materials 1.205 - 206 (2002) At equilibrium, why would small crystals get smaller and bigger crystals get bigger? (Grey and Green are the same molecules, just from different crystals) A. The molecules at the periphery have less enthalpic stabilization. Ostwald ripening maximizes enthalpic stabilization B. The molecules at the periphery of the...

Do a ring flip of both *Draw the two conformation of the cis and trans cyclohexane structures above *List the number of axial and equatorial substituents for both the cis and trans *Which isomer is more stable overall, cis or trans? Why? 2. Make a model cis-1,3-dimethylcyclohexane and trans-1,3-dimethylcyclohexane. Do a ring flip *Draw the two conformation of the cis and trans cyclohexane structures above *List the number...
