Partial credit will be minimal, so read the questions carefully and weigh your answers critically. THINK BEFORE YOU WRITE; most answers require only a few well-chosen structures, and extraneous wrong answers may lose points. You need not show lone pairs, but be sure that structures satisfy the octet rule, if possible. Show connectivity unambiguously with Lewis/Kekule structures or "condensed" (CH n ) structures; only for cyclic molecules may you use bond-line ("zigzag") drawings. Where stereochemistry is relevant, show stereoisomers unambiguously, with chair cyclohexanes or with wedges and dotted lines, on carbons that look tetrahedral and in staggered conformations (no linear C- C-C, Fischer projections, or "bowties"). Do not duplicate structures. If a product is racemic, you need not draw both enantiomers; instead you may draw one and write "racemic" or "plus mirror image" or "+MI".
