Unformatted text preview: 3 H 3 C H H OH Cl These are correct. All these are the same compounds, and the difference between these is just rotation. Cl C CH 3 C H OH H 3 C H Cl C CH 3 C H OH H 3 C H Cl needs only one bond, and here there are two ---> incorrect C needs four bonds, and here there are three ---> incorrect 6. When you draw condensed formula, cyclic structures (including rings) should show bonds to make rings. Straight chains do not show bonds in the backbone. However, rings have to show bonds (e.g., 1-19.c) C C C C H H H H H H HC HC CH 2 CH 2 correct CH=CHCH 2 CH 2 incorrect These two ends have to meet each other to make a ring, moreover these two don't make enough # of bonds. They make only 3 bonds aroung each carbon. No sense....
