Practice Exercises Draw Newman projections for these staggered and three eclipsed conformations of 1, 2 - dichlorobutane as viewed downt he central C-C bond. (a) The . Practice Exercises Draw Newman projections for these staggered and three eclipsed conformations of 1, 2 - dichlorobutane as viewed downt he central C-C bond. (a) The more stable conformation is the one with the t-b-tyl substituent equatorial and the methyl substituent axial. 6. Chair conformations (which will be covered next) can be understood if one understands Newman projections. Take a look at the below Newman-type conformation, where two hydrogens are labeled Ha and Hb in the chair and Newman projections. (A) Try to map the remaining hydrogen atoms to one-another. (B) Draw a Newman projection-. 1. a. Draw the Newman Projection of each ethane. Label each as either “staggered” or eclipsed. b. Circle the less energy (more stable) conformation above and explain the phenomenon that increases the energy of the other conformation. 2. Identify whether each pair of compounds are constitutional isomers, stereoisomers, or identical. a). 1. a. Draw the Newman Projection of each ethane. Label each as either “staggered” or eclipsed. b. Circle the less energy (more stable) conformation above and explain the phenomenon that increases the energy of the other conformation. 2. Identify whether each pair of compounds are constitutional isomers, stereoisomers, or identical. a). Newman Projections and Cyclohexane Chairs. Steps. 1! On the left-most carbon, put your first substituent in on both chairs. It should be equatorial in the “right-handed” chair, and axial in the other. Are the two substituents eq/eq, eq/ax, or ax/ax? This will help recognize relative stability. CONFORMATIONAL ANALYSIS – PRACTICE EXERCISES 1) Draw a Newman projection of the most stable conformation of 2-methylpropane. 2) The structures below are: H H H H CH3 CH3 H H CH3 H H CH3 A) not isomers. B) conformational isomers. C) cis-trans isomers. D) structural isomers. E) both B and D 3) Define the term conformation.
