as
the N of aniline has an electron pair, it will attract the
anhydride which will break into CH3CO+ +
CH3COO-. The CH3CO+
will be attracted by the electron pair of aniline.

aniline? you differentiate based on IR spectrum, that your compound is acetanilide and not undicate which key absorptions lead you to your conclusions) (Relevant IR spectral frequency chart is provided to you at the back) (b) The starting material dissolves in dilute HCI, but the product acetanilide does not. Why? (c) Explain why the acetylation requires one mole of acetic anhydride per mole of aniline, though acetic anhydride contains two acetyl groups. How is the by-product containing...

1. Which of the following statement is consistent with the mechanism between the starting material, 4-aminophenol and acetic anhydride, used to synthesized 4-acetamidophenol. A) Acetic anhydride acts as a nucleophile attacking the alcohol group in 4-aminophenol. B) The alcohol group of 4-aminophenol acts as a nucleophile attacking the carbonyl carbon of acetic anhydride. C) The amine group of 4-aminophenol acts as a nucleophile attacking the carbonyl carbon of acetic anhydride. D) Acetic anhydride acts as a nucleophile attacking the amine...

Synthesis of Acetanilide Acetanilide is synthesized from aniline by a reaction known as acylation. Acylation is the addition of an acyl group to a compound. In this experiment, aniline (1 amine) is reacted with acetic anhydride (acylating agent) to form acetanilide (an amide). H-C-CH3 + CH...

Hint-there should be three steps, with two arrows in each step the mechanism for the reaction of the alcohol and the anhydride, assuming it occurred after the 6 pts) if 4) Draw the most favorable conformation of the diene starting material. What implication does this have for the energy of the reaction? (2 pts) 5) Cyclopentene could be used in this reaction in place of...

Answer ALL parts a)-e). You are given an experimental procedure in which aniline reacts with acetic anhydride to give acetanilide as shown below. The procedure uses 5.9 g of aniline and 6.3 g of acetic anhydride. aniline, M, 93 acetic anhydride, M, 102 acetanilide, M, 135 Calculate which of the reagents is limiting, and hence determine the maximum possible yield of acetanilide in grams. Show your working a) Based on your answer to part a), describe how you would remove...
