Unformatted text preview: 6. Exer. 7-7: +10 each, 0 for any structure with nonoctet atom, -5 for connection to wrong atom (e.g.,-OCH 3 CH 2 or -CH 3 CH 2 O), -5 for skeletal/zigzag structure, 0 if does not match molecular formula or if connectivity is wrong (e.g. -CH 2 CH 2 OH); lone pairs unnecessary. 7. Prob. 5.53b: +15 each, -10 for each wrong or duplicated stereoisomer (minimum total 0). 8. Prob. 7-44a!: +10 each reagent (light, heat, cation unnecessary), no credit for Br (but 2 Br· from h ν OK), Cl, Cl 2 , I, I 2 or for redundant (Cl 2 , then Br 2 , but NaCl followed by NaI OK); +10 bonus for both correct (also for Cl 2 then I-). Reagents can be in any boxes if in correct order. If you think your exam has been misgraded, return it to your TA with an explanatory note. MAKE NO MARKS ON YOUR EXAM!...
