Amines Questions and Answers

Write a balanced equation for the decomposition of ammonium nitrate to form molecular nitrogen, and water. (Hint: Balance oxygen last, since it is present in more than one molecule on molecular oxygen, the right side of the equation.)

Draw the condensed structure of a primary amine with 2 carbon atoms, and no double or triple bonds.

Humans cannot digest cellulose because they A. lack the necessary enzymes to digest beta-glcosides B. cannot digest chlorophyll C. are poisoned by beta-glycosides D. are allergic to beta-glycosides E. have intestinal flora which use up beta-glycosides

What is the name of this compound? A) 1-methyl-5-bromoaniline B) N-methyl-3-bromoaniline C) N-methyl-p-bromoaniline D) 1-bromo-3-N-methylamine benzene E) 1-brotno-3-N-methyl aniline

Learning Goal: In the presence of a strong acid, such as HCl, an amide reacts with water to produce a carboxylic acid and an ammonium or amine salt. In the presence of a strong base, like NaOH, the amide reacts to produce ammonia or an amine, and a carboxylic acid salt. Acetaminophen is an analgesic marketed under the brand name Tylenol, among others. (Figure 1) Draw the amine that results from the base hydrolysis of acetaminophen.

Which of the following is the first step in the Gabriel synthesis of primary amines? Deprotonation of phthalimide. Nucleophilic substitution. Hydrolysis of the phthalimide derivative. Deprotonation of the ammonium salt.

5. Write the condensed (or line-angle) structural formula for the following compounds: a. 2,2-dimethyl-1-propanamine b. 4-methyl-2-pentanamine c. N-isopropyl-2-butanamine d. 2-bromoaniline e. N-cyclohexylethanamide f. benzamide g. N-methylhexanamide h. N-butyl,N-methylpropanamide

Draw the condensed structure of a 3° amine with 4 carbon atoms, and no double or triple bonds.

Draw the condensed structure of a primary amine with 3 carbon atoms, and no double or triple bonds.

Draw the Lewis structure for ethylamine (C2H7N). Ethylamine molecules have one amino group. Be certain you include any lone pairs.

Which of the following is not true about nucleophilic acyl substitution reactions with an acid anhydride (assuming that the required acid or base catalyst is present when needed)? Ammonia can serve as the nucleophile reacting with the anhydride to form an amide Chloride ion can serve as the nucleophile reacting with the anhydride to form an acyl chloride Water (with heat) can serve as the nucleophile reacting with the anhydride to form carboxylic acids Methanol can serve as the nucleophile reacting with the anhydride to form a methyl ester
