Use your molecular modeling kit to determine the absolute configurations of the following compounds. Define each stereocenter as either (R) or (S). If the molecule does not have a stereocenter select "achiral". (For extra UNGRADED practice, you could name these compounds fully.) H. H. CH2CH3 H3C H3CH2C HOCH2CH3 CH3 CH3 OH CH2CH3

1. Draw the correct skeletal structure of 4,4-dibromo-1-butanol: : draw its most stable conformer looking along C2-C3 the Newman projection to differentiate them from methyl groups and draw all the carbons skeletal and on the Newman Projection provided Draw the hydrogens that are directly connected to draw the correct skeletal structure here , draw its and then in the 2. For (1R, 2S, 4R)-4-tert-buyl-1-ethyl-2-methylcyclohexane: draw its correct skeletal structure most stable conformer first showing the Hydrogens that are directly attached to the ring last stusture omit the hydrogens that are directly connected to the ring and draw the correct positions of the three alkyl groups in skeletal representation : Draw all bonds with the same length! draw the correct skeletal structure here showing stereochemistry this chair draw the most stable confomer including the H's directly attached to the ring on this chair draw only the alkyl groups, all bonds same lenght
