- Indicate whether the following statement is true or false. Aliphatic amines are more basic than ammonia, whereas aromatic amines are less basic than ammonia. When amines are reacted with bases, they form ammonium salts. Benzenesulfonyl chloride or p-toluenesulfonylchloride give N-substituted sulfonamides with primary and secondary amines. Derivative of primary amines is insoluble in dilute NaOHarrow_forwardBarbiturates are prepared by treatment of diethyl malonate or a derivative of diethyl malonate with urea in the presence of sodium ethoxide as a catalyst. Following is an equation for the preparation of barbital, a long-duration hypnotic and sedative, from diethyl diethylmalonate an urea. Barbital is prescribed under one of a dozen or more trade names. Propose a mechanism for This reaction The pKa of barbital is 7.4. Which is the most acidic hydrogen in this molecule and how do you account for its acidity?arrow_forwardIn the 1880's, Acetanilide, sold under the name Antifebrin, was widely used as a pain reliever and fever reducer. However, it had many adverse side effects, including cyanosis as a result of methemoglobinemia. The toxic side effects were the result of a small portion of acetanilide being hydrolyzed to aniline. Acetanilide was discontinued and replaced with phenacetin. Later studies show that both acetanilide and phenacetin are metabolized to acetaminophen. This metabolite, which we know as Tylenol, is responsible for the analgesic and antipyretic properties.
