-Know the reaction mechanism for all chemistry in this lab (forming the acid chloride, then the amide/anilide/toluidide derivative). -Understand how choosing a derivative and measuring its melting point allows us to narrow down the identity of an unknown carboxylic acid. How do you know which derivative is the best one to make? -Be able to calculate percent and theoretical yields.

Suppose you took your two compounds, dissolved them in tertbutyl methyl ether and then added them to a separatory funnel.  Now suppose you add in aqueous sodium bicarbonate and vigorusly shake the contents of the separatory funnel. ethanol will be dissolved in tert butyl methyl ether ether and valeric acid will be dissolved in the aqueous sodium bicarbonate layer. Draw the EXACT chemical structure that will exist in each of the layers after shaking with sodium bicarbonate.  (Is it neutral or charged?)

Write a mechanism that accounts for the formation of ethyl isopropyl ether as one of the products in the following reaction. A. Write the mechanism for step one of this reaction. Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond.   B. Write the mechanism for step two of this reaction (where the product of step one reacts with the solvent, ethanol). Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond.   C.Write the mechanism for the last step of this reaction (formation of ethyl isopropyl ether). Show lone pairs and formal charges. Only the acidic hydrogen should be drawn out with a covalent bond. Cl- will act as the base in this reaction.

Please solve both parts qs, will provide helpful ratings.

1. Suppose you want to study the influence of IO3- concentration on the rate of the reaction used in Part A. Which of the following procedures would be appropriate? a. Use different amounts of KIO3 solution with a constant amount of water and a constant amounts of NaHSO3 solution. b. Use different amounts of KIO3 solution, constant amounts of NaHSO3 solution, and different water amounts to give a constant total amount. c. Use different amounts of KIO3 solution, different amounts of NaHSO3 solution, and constant amounts of water. Explain your answer: The answer is B, I just need an explanation on why

Preamble: A student chemist in an attempt to synthesise compound B from the aromatic aldehyde.  24. What is the reaction name for the chemical transformation of A to BA. reductive aminationB. catalytic reductionC. carbonyl dehydrationD. Hofmann eliminationE. Aldehyde rearrangement

In Chapter 18, we will learn about the hydrolysis of acetals to aldehydes and ketones. Four of the seven steps in the mechanism for this process are shown in the conversion of acetal A to hemiacetal E. a.Add curved arrows for each step. b.Draw another resonance structure for C. c.Identify the nucleophile and electrophile in Step [3]. d.Which steps are Brønsted–Lowry acid–base reactions?

The following test on compounds X and Y were done and the results, list the observations in the table below. Complete the inferences for each test.

The question is:    Consider a mixture containing 0.5 benzil and 0.05 biphenyl. Your task is to isolate the benzil in pure form. Would this be best accomplished by recrystallization or extraction?  I don’t really know which one would be better cause both can isolate a substance in its pure form. Thanks!

In this lab you used acid/base extraction to remove acidic impurities, how could basic impurities be removed through extraction? Imagine the two compounds below are both dissolved in ethyl acetate (a standard organic solvent for extractions), create a diagram/flow chart that outlines steps that could be taken to separate them through acid/base extraction and recover each compound in its neutral Be sure to track when each compound is in the organic or aqueous layer.
