Monday Night Problem Set 2 M LECULAR MODELING 1) Construct the molecule ethane, CH 3 CH 3 . a) How many sets of equivalent hydrogen atoms are found in ethane? only one b) Draw a three-dimensional representation of ethane. On your drawing, indicate the bond angles about each carbon atom. CC H H H H H H 109 o c) Draw a staggered and eclipsed Newman projection for ethane. H H H H H H H H H H H H Staggered Eclipsed d) If you replace one of the hydrogen atoms in ethane with a chlorine atom, you get a molecule called chloroethane. Draw the three-dimensional structure below. On your structure, use the δ + and δ - notation to indicate the direction of the bond polarity in the C-Cl bond. Cl H H H H H δ - δ + How many sets of equivalent hydrogen atoms are found in chloroethane? 2 e) Now replace a second hydrogen with another chlorine atom. How many different structures can you make? Draw all of the isomers below. Cl Cl H H H H H H Cl H H Only twostructural isomers are possible. ..
