Organic Chemistry
- a. Compound X is benzene, Y is acetic anhydride acid. Complete the following scheme and determine Z! b. Determine which reagents except acetic acid anhydrides can replace Y!arrow_forwardThe hydrolysis of the ester shown here is catalyzed by morpholine. Explain how morpholine catalyzes the reaction. (Hint: The pKa of the conjugateacid of morpholine is 9.3, so morpholine is too weak a base to function as a base catalyst.)arrow_forwardFollowing is an outline of a synthesis of the bronchodilator carbuterol, a beta-2 adrenergic blocker with high selectivity for airway smooth muscle receptors. Q.Suggest a structural relationship between carbuterol and ephedrinearrow_forward
- Explain this statement: Although 2-methoxyacetic acid (CH3OCH2COOH) is a stronger acid than acetic acid (CH3COOH), p-methoxybenzoic acid (CH3OC6H4COOH) is a weaker acid than benzoic acid (C6H5COOH).arrow_forwardExplain this statement: Although 2-methoxyacetic acid (CH3OCH2COOH)is a stronger acid than acetic acid (CH3COOH), p-methoxybenzoic acid(CH3OC6H4COOH) is a weaker acid than benzoic acid (C6H5COOH).arrow_forwardThe pKa, of the conjugate acid of morpholine is 8.33. (a) Calculate the ratio of morpholine to morpholinium ion in aqueous solution at pH 7.0. (b) At what pH are the concentrations of morpholine and morpholinium ion equal?arrow_forward
- What is the conjugate acid of acetamide and its pka value?arrow_forwardAliphatic amines are more basic than ammonia, whereas aromatic amines are less basic than ammonia. Is that true or false?arrow_forward(a) Arrange the following compounds in an increasing order of their indicated property :(i) Benzoic acid, 4-Nitrobenzoic acid, 3,4-Dinitrobenzoic acid, 4-Methoxybenzoic acid (acid strength)(ii) CH3CH2CH (Br) COOH, CH3CH (Br) CH2COOH,(CH3)2CHCOOH, CH3CH2CH2COOH (acid strength)(b) How would you bring about the following conversions :(i) Propanone to Propene (ii) Benzoic acid to Benzaldehyde(iii) Bromobenzene to 1-phenylethanolarrow_forward
- When acetophenone, hydroxelamine hydrochloride, and sodium hydroxide are reacted to synthesize acetophenone oxime, why is it necessary to add hydrochloric acid after the reaction to make it acidic?arrow_forwardTreatment of pentanedioic (glutaric) anhydride with ammonia at elevated temperature leads to a compound of molecular formula C5H7NO2. What is the structure of this product? [Hint: You need to think about the reactivity not only of acid anhydrides but also of amides and carboxylic acids]arrow_forwardRank the following compounds in order of increasing basicity: I. p-nitroaniline III. N-methylaniline II. p-aminobenzaldehyde IV. p-methylanilinearrow_forward
