2. Draw the structure of the major organic product that is formed from the following reaction. Draw this structure in the box at the bottom of the next page. Then use letters to label all the sets of chemically equivalent carbons in this structure. The broadband proton-decoupled 13C NMR spectrum of the product is shown below. DEPT 90 and DEPT 135 data are included in the table on the following page. Use this spectroscopic data to make clear assignments of...
1. Use the following structure to draw Newman Projections (each subsequent projection with the back carbon rotated 60" clockwise), Label the projection that is highest in energy and lowest in energy. Explicitly label all H's and CHY's. The arrow denotes the "front" carbon. Use this position to start your first Newman Projection Hae H | 改改改改 2. Finish each Newman Projection to correctly represent the following molecule in the box. OH Br CH3 0月
