Document Summary
Credit: nomenclature, 2d lewis structures, 3d structures, formal charge & resonance, formulas, functional groups & special nomenclature. Do your best to show me what you know in the available time. The immediate is often the enemy of the ultimate. 2: provide an acceptable name for the following structure. (25 pts) Oh: draw an acceptable 2d lewis structure for the following formula. Indicate any formal charges present, all lone pair electrons and completely draw out all atoms (e. g. do not write ch3). (20 pts) six carbon ring has formal charge (ch3)hnocchc(och3)chcncochnh2chohch2ccc6h4c(ch3)2ch(cho)co2ch2ch(no2)co2h. 3: first, draw three other reasonable 2d resonance structures that delocalize the positive charge. Rank your structures from best (= 1) to poorest. Draw two dots for lone pair and pi bond electrons. Indicate any formal charge present and give the hybridization, bond angles and shape of each nonhydrogen atom (below). Assume that all non-hydrogen atoms have full octets, unless a carbocation is written. (30 pts) g.
