Question 1

Use the following to answer the questions below:
In each of the following multiple-choice questions, characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices:
-Statements: (1) The reaction of an amine with water produces a basic solution.
(2) Acetamide is a one-carbon amide, and ethanamide is a two-carbon amide.
(3) The most common type of polyamide is a polyurethane.

Accepted Answer

Statement 1 is true because amines react with water to form hydroxide ions, making the solution basic. Statement 2 is false because acetamide is a two-carbon amide (CH3CONH2), and ethanamide, another name for acetamide, is also a two-carbon amide, not a one-carbon amide. Statement 3 is false because the most common type of polyamide is nylon, not polyurethane, which is a different class of polymers.

Question 2

Use the following to answer the questions below:
For each set of reactants, select from the response list a product of the reaction. Responses may be used more than once or need not be used at all.

-Primary amine, Carboxylic acid

Accepted Answer

When a primary amine reacts with a carboxylic acid, an amide is formed through a condensation reaction. The amide has a carbonyl group (-CO-) bonded to nitrogen (-NH2) group.

Question 3

Use the following to answer the questions below:
In each of the following multiple-choice questions, characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices:
-Statements: (1) The compounds 1-butanamine and butanamide are constitutional isomers.
(2) The reaction of an alkyl halide with ammonia produces a primary amine.
(3) In the hydrolysis of an amide, a carbon-nitrogen single bond is broken.

Accepted Answer

Statement 1 is false because 1-butanamine and butanamide are functional isomers, not constitutional isomers. Statement 2 is true; reacting an alkyl halide with ammonia typically yields a primary amine. Statement 3 is also true; hydrolysis of an amide involves breaking a carbon-nitrogen single bond.

Question 4

Use the following to answer the questions below: In each of the following multiple-choice questions, characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices: -Statements: (1) Acidic hydrolysis of an amide produces an acid salt and an amine. (2) The amide urea contains more nitrogen atoms than carbon atoms. (3) All cyclic amines are heterocyclic compounds that are either 1⁰ or 2⁰ amines.

Accepted Answer

- Statement 1 is FALSE because acidic hydrolysis of an amide produces a carboxylic acid (not an acid salt) and an ammonium salt.- Statement 2 is TRUE as urea (NH2)2CO contains two nitrogen atoms and one carbon atom.- Statement 3 is FALSE because not all cyclic amines are heterocyclic compounds that fit the specific classification mentioned; cyclic amines can vary widely in structure.

Question 5

Use the following to answer the questions below: In each of the following multiple-choice questions, characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices: -Statements: (1) In the presence of a strong base, a primary amine can be converted to a secondary amine by reaction with an alkyl halide. (2) Morphine, codeine, and heroin are all naturally-occurring alkaloids. (3) Two -NH₂ groupings are present in each of the compounds 1,4-butanediamine and 3-aminobutanamide.

Accepted Answer

1) True: This describes the alkylation of amines, a common reaction in organic chemistry where a primary amine reacts with an alkyl halide to form a secondary amine. 2) False: While morphine and codeine are naturally occurring alkaloids, heroin is synthesized from morphine. 3) True: Both 1,4-butanediamine and 3-aminobutanamide contain two -NH2 groups in their structures.

Question 6

Use the following to answer the questions below:
For each of the compounds, choose from the response list a correct comment concerning the compound's structure. Responses may be used more than once or need not be used at all.
-N-methylaniline

Accepted Answer

N-methylaniline contains a nitrogen atom bonded to two carbon atoms, which is characteristic of aniline derivatives. It also contains six carbon atoms and one nitrogen atom, so it does not have the same number of carbon and nitrogen atoms (choice C is incorrect). Choice B is also incorrect since N-methylaniline has six carbon atoms, not three.

Question 7

Use the following to answer the questions below:
For each set of reactants, select from the response list a product of the reaction. Responses may be used more than once or need not be used at all.

-Amide, Water, Hydrochloric acid

Accepted Answer

When amide is reacted with water and hydrochloric acid, an amine salt is produced. The amide molecule is hydrolyzed by water to produce an ammonium ion and a hydroxide ion, and the ammonium ion is then protonated by hydrochloric acid to form an ammonium chloride salt, which is an amine salt.

Question 8

Use the following to answer the questions below:
For each of the compounds, select a correct classification from the response list. Responses may be used more than once or need not be used at all.

-Benzamide

Accepted Answer

The answer of Use the following to answer the questions...

Question 9

Use the following to answer the questions below:
For each set of reactants, select from the response list a product of the reaction. Responses may be used more than once or need not be used at all.

-Primary amine, Alkyl halide, Sodium hydroxide

Accepted Answer

The reaction between a primary amine and an alkyl halide in the presence of sodium hydroxide typically results in the formation of a secondary amine through nucleophilic substitution.

Question 10

Use the following to answer the questions below:
In each of the following multiple-choice questions, characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices:
-Statements: (1) Caffeine is a central nervous system stimulant whose mode of action is enzyme inhibition.
(2) Theobromine is an alkaloid found in chocolate.
(3) Acetaminophen is a substituted acetamide whose structure includes a benzene ring.

Accepted Answer

(1) True - Caffeine is a central nervous system stimulant and it works by blocking the action of adenosine, a neurotransmitter that relaxes the brain and causes drowsiness.
(2) True - Theobromine is an alkaloid found in chocolate.
(3) True - Acetaminophen is a substituted acetamide and its structure includes a benzene ring.

Question 11

Use the following to answer the questions below:
For each set of reactants, select from the response list a product of the reaction. Responses may be used more than once or need not be used at all.

-Primary amine, Hydrochloric acid

Accepted Answer

When a primary amine reacts with hydrochloric acid, it forms an amine salt (also known as a quaternary ammonium salt) as a product. This is because the amine group (–NH2) of the primary amine reacts with the H+ ion of the hydrochloric acid, forming an ammonium ion (–NH3+) and a chloride ion (Cl–) which then attract each other to form the amine salt.

Question 12

Use the following to answer the questions below:
For each set of reactants, select from the response list a product of the reaction. Responses may be used more than once or need not be used at all.

-Amine salt, Sodium hydroxide

Accepted Answer

When an amine salt reacts with sodium hydroxide, the base (sodium hydroxide) neutralizes the acid part of the amine salt, releasing the free amine. This is a typical acid-base reaction where the base (NaOH) frees the amine from its salt form.

Question 13

Use the following to answer the questions below:
For each of the compounds, choose from the response list a correct comment concerning the compound's structure. Responses may be used more than once or need not be used at all.
-N-methylformamide

Accepted Answer

N-methylformamide contains one nitrogen atom and one carbon atom from the formamide group, and one additional carbon atom from the methyl group, making the number of carbon and nitrogen atoms equal.

Question 14

Use the following to answer the questions below:
For each of the compounds, choose from the response list a correct comment concerning the compound's structure. Responses may be used more than once or need not be used at all.
-Methanamine

Accepted Answer

Methanamine has the formula CH3NH2, which means it contains one carbon atom and one nitrogen atom, thus having the same number of carbon and nitrogen atoms.
