1. Draw Kekule structures for the following, showing all non-bonding electrons: a) \( \mathrm{CHCl}_{3} \) b) \( \mathrm{H}_{2} \mathrm{~S} \) c) \( \mathrm{CH}_{3} \mathrm{NH}_{2} \) d) \( \mathrm{NaH} \) e) \( \mathrm{CH}_{3} \mathrm{Li} \) 2. Why can't an organic molecule have the formula \( \mathrm{C}_{2} \mathrm{H}_{7} \) ? 3. Draw a Line-bond (Kekule) and a skeletal structure for acetaldehyde \( \mathrm{CH}_{3} \mathrm{CHO} \). 4. Convert the following structures into molecular formulas. 5. Convert the following molecular formulae into Kekule structures. a) \( \mathrm{C}_{3} \mathrm{H}_{8} \) b) \( \mathrm{CH}_{5} \mathrm{~N} \) c) \( \mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O} \) (2 possible) d) \( \mathrm{C}_{3} \mathrm{H}_{7} \mathrm{Br} \) (2 possible) e) \( \mathrm{C}_{2} \mathrm{H}_{4} \mathrm{O}(3 \) possible) f) \( \mathrm{C}_{3} \mathrm{H}_{9} \mathrm{~N} \) (4 possible) 6. Identify the bonds in the following compounds as either ionic, polar covalent, or non-polar covalent (hint: what are EN values?). a) \( \mathrm{NaCl} \) b) \( \mathrm{CH}_{3} \mathrm{Cl} \) c) \( \mathrm{Cl}_{2} \) d) \( \mathrm{HOCl} \) 7. Draw as many possible Kekule structures as you can from the formula \( \mathrm{C}_{1} \mathrm{H}_{14} \) (Hint: start first with a single chain, then add branches). 8. Convert the following skeletal structures into condensed structural formulas and molecular formulas.
