An amino group ($$-NH)$$

Question 2

The device shown in the image is used to deliver a life-saving dose of epinephrine. Which class of organic compounds does epinephrine belong to, based on its functional group?

Accepted Answer

Amines

Question 3

Why are amines, such as those found in epinephrine, often associated with strong odors?

Accepted Answer

They are derivatives of ammonia, which has a strong odor.

Question 4

Which of the following best describes the classification of the amine group in epinephrine?

Accepted Answer

Secondary amine

Question 5

A person with a severe allergy carries the device shown in the image. The active ingredient contains an amine group. Which property of amines makes them suitable for rapid physiological response?

Accepted Answer

Ability to form hydrogen bonds

Question 6

Which of the following reactions is used to synthesize a primary amine such as ethanamine, a structural analog to the amine group in epinephrine?

Accepted Answer

$$\mathrm{CH_3CH_2I + NH_3$ \rightarrow CH_3CH_2NH_2 + HI}$$

Question 7

Which of the following statements about the solubility of small amines, such as those found in medications, is correct?

Accepted Answer

They are soluble in water because the nitrogen atom forms hydrogen bonds with water.

Question 8

Which of the following best explains why tertiary amines have lower boiling points than primary amines of similar size?

Accepted Answer

Tertiary amines cannot form hydrogen bonds between their molecules.

Question 9

Which of the following is the correct IUPAC name for the compound with the structure $$\mathrm{CH_3CH_2NH_2}$$?

Accepted Answer

Ethanamine

Question 10

Which of the following best describes the reaction that forms an amide from a carboxylic acid and an amine?

Accepted Answer

Condensation reaction

Question 11

Which of the following is the correct name for the amide formed from methanamine and butanoic acid?

Accepted Answer

N-methylbutanamide

Question 12

Which of the following is a correct structural formula equation for the formation of N,N-diethylethanamide?

Accepted Answer

$$\mathrm{CH_3COOH + (C_2H_5)_2NH \rightarrow CH_3CON(C_2H_5)_2 + H_2O}$$

Question 13

Which of the following best describes the difference between an amide and an ester?

Accepted Answer

An amide has a nitrogen atom bonded to a carbonyl group, while an ester has an oxygen atom bonded to a carbonyl group.

Question 14

Which of the following is the correct IUPAC name for the compound $$\mathrm{NH_2$(CH_2$)_5NH_2}$$?

Accepted Answer

Pentane-1,5-diamine

Question 15
