Homework Answers
a. Novacaine is usually used in the form of the hydrochloride salt (also called procaine HCl) because it is highly water-soluble. Procaine hydrochloride, when taken orally, enters the body by being mainly absorbed through the villi in the small intestine.
b. The tertiary nitrogen atom is the stronger base. The lone pair of the aniline nitrogen is delocalized into the aromatic ring and stabilized by resonance, so it is a weaker base than the tertiary nitrogen atom.
Hence, this tertiary atom with bind with H to make the ammonium salt

molecule c molecule d QUESTION 6 Absorption of drugs into the body is based on multiple factors including ionization state, surface area of the stomach and intestines, and other physical properties of the drug. A novel drug contains a carboxylic acid functional group with a pKa value of 3.24.. Based on ionization states alone, would you predict that it is better absorbed (ie passes through a lipid membrane) in the stomach where the pH is about 2, or...
