A molecule of unknown structure has a molecular formula of C,H¿O,. In the infrared spectrum there are absorptions at 1761, 1145, and 761 cm-!. In the 13C NMR spectrum, there are absorptions at ô 168.4, 152.0, 128.2, 128.0, 124.3, 122.8, 116.8, 29.1 and 23.6. In the 'H NMR spectrum, between ô 7.2 and 7.0, there is a complicated pattern that integrates to 4 protons. Additionally, there are triplets at ô 3.0 and 2.7, each integrating to 2 protons. Identify the structure of

I believe the Henderson-Hasselbalch Equation is supposed to be used here, but I am lost and I am not sure. Pls help. Thank you!

First, add curved arrow(s) to show the resonance using the following pattern: an allylic lone pair. Modify the second structure given to draw the new resonance structure. Include lone pairs and charges in your structure. Use the + and - tools to increase or decrease the charge on an atom, and use the single bond tool to add/remove double bonds.   What am I missing here? I've tried putting charges in various spots and still can't get it.

Solve correctly please. With explanation.

On the molecules on the back page, circle and label all of the functional groups that you see (identified in the table above). Please note the following tips that may help you on this assignment: If a molecule contains –COOH, or a C double bonded to an O and single-bonded to an –OH, the functional group you circle is only the carboxyl, not a carboxyl, carbonyl, and hydroxyl separately). Phosphate groups are tricky – any P surrounded by 4 O’s is a phosphate – adjacent phosphates may share an O, and sometimes the O is in the form of OH. There is often shorthand that is used in drawing these structures – if you see a jagged line or ring structure, assume that carbon is at each corner. There may be ionized forms of the functional groups above (such as NH2 or NH3+) – these are the same functional groups. The order of the atoms in the functional group may be switched, depending on which side of the molecule it is on. For example, “—NH3” and “H3N—“  are the same thing.

Draw both resonance structures of the anion formed by the reaction of the most acidic C-H bond of the compound below with base. • Include all valence lone pairs in your answer. . For structures having different hydrogens of comparable acidity, assume that the reaction occurs at the less-substituted carbon. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate resonance structures using the symbol from the drop-down menu. 0- O Bi % 5 T G ▾ 99-85 A 6 SCH₂CH3 ChemDoodleⓇ Cengage Learning Cengage Technical Support Y H F6 On [F & 7 O U J F7 * 8 PrtScn | K Home 9 83°F Sunny O L A End 0 F10 P IN Previous Next> C 4x PgUp F11 J Save and Exit 9:38 AM 7/18/2022 PgDn + = F12 80
