PQ-7. What is the concentration of the bromide ion if 25.0 mL of a 0.50 M AIB13 solution combines with 40.0 mL of a 0.35 M NaBr solution? Assume volumes are additive. (A) 7.9×10 mol·L- (B) 0.41 mol·L- (C) 0.79 mol·L! (D) 2.1 mol·L

( do 1 and 2 with mechanism)

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.

3) Any compound or ion with at least one lone pair can be considered a base and/or a nucleophile. The relative basicity and nucleophilicity of the species is one of the most important factors that determine the mechanism of a reaction on sp³-carbon atoms. Please show an example of a) a reagent that is a strong nucleophile and a strong base, b) a reagent that is a weak nucleophile and a strong base, c) a reagent that is a strong nucleophile and a weak base, d) a reagent that is a weak nucleophile and a weak base. Which nitrogen atom in the structure below is most nucleophilic? Please explain by discussing the electron density around each nitrogen atom. Show at least three resonance structures of the compound. N.

Show the mechanism for the forward acid-base reactions only. In other words, use arrow formalism to track electrons. Acid-base mechanismstypicallyrequire two arrows, flowing in the same direction.Refer to your notesfor proper arrow direction and flow, if necessary. It should be obvious which is the acid and which is the base.

What does In-situ mean in the case of In-situ reaction? example down below Benzyne is a highly reactive organic molecule that has not been isolated. It is prepared in situ reaction. Its instability is the result of its triple bond.

Organic Chemistry 1 Explain all of the steps clearly and logically. Do not just draw a picture. Clearly explain your answer in a step-by-step fashion. Here is the instructor's solution (answer/explanation) to the problem. Please read the professor's solution carefully and explain it here.

Fill in the blank. Please choose from the following terms - copy+paste the correct term into the blank (don't alter the spelling). primary, secondary, tertiary, inversion, retention, nucleophile, base, regioselective, stereoselective, Zaitsev, Hoffman, E1, E2, antiperiplanar, trans, cis, polar aprotic, polar protic, racemic mixture E2 reactions are regioselective and general favor the more substituted alkene called the product.

i.) Ester hydrolysis can occur in acidic or basic conditions. Predict the product AND show the mechanism for the following addition/elimination reactions. Note that the first reaction is acid catalyzed and the second reaction is based catalyzed a.) " b.) مل NaOH H3O+ c.) Explain why an acid chloride reacts in neutral conditions to form the same product as 1 and 2 above. Show the mechanism for this hydrolysis reaction. WHY IS THIS REACTION NOT AN EQUILIBRIUM REACTION? CI H₂O
