Chapter 2: Q. 57P (page 141)

Many naturally occurring compounds contain more than one functional group. Identify the functional groups in the following compounds

  1. Penicillin G is a naturally occurring antibiotic.
  2. Dopamine is the neurotransmitter that is deficient in Parkinson鈥檚 disease.
  3. Capsaicin gives the fiery taste to chili peppers.
  4. Thyroxine is the principal thyroid hormone.
  5. Testosterone is a male sex hormone.

Short Answer

Expert verified

(a)Functional groups present in penicillin G are the Amide group; carboxylic acid group; amine group, and thioether group.

(b)Functional groups present in Dopamine are the Amine group and the hydroxyl group.

(c)Functional groups present in Capsaicin are the Amide group; ether group; hydroxyl group.

(d)Functional groups present in Thyroxine are ether group; amine group; carboxylic acid group; hydroxyl group.

(e)Functional groups present in Testosterone are the carbonyl (ketone) group; hydroxyl group.

Step by step solution

01

Functional groups

Functional groups are groups of atoms in a molecule that have their own characteristic properties, irrespective of the other atoms present in a molecule. A few examples of functional groups are alcohols, amines, carboxylic acids, ketones, and ethers.

02

Functional groups in penicillin

In penicillin G, the functional groups are Amide group (-CONH); carboxylic acid group (-COOH); amine group (R-N-R), thioether group (R-S-R).

03

Functional groups in Dopamine

In Dopamine, the functional groups are the Amine group (R-NH2) and the hydroxyl group (-OH).

04

Functional groups in Capsaicin

In Capsaicin, the functional groups are the Amide group(-CONH); ether group (R-O-R); hydroxyl group (-OH).

05

Functional groups in Thyroxine

In Thyroxine are ether group(R-O-R); amine group(R-NH2); carboxylic acidgroup(-COOH); hydroxyl group(-OH).

06

Functional groups in testosterone

In Testosterone, the functional groups are the carbonyl (ketone) group (R-CO-R); hydroxyl group (-OH).

In each reaction, label the reactants as Lewis acids (electrophiles) or Lewis bases (nucleophiles). Use curved arrows to show the movement of electron pairs in the reaction. Draw any nonbonding electrons to show how they participate in the reactions.

N-Methylpyrrolidine has a boiling point of81慰C, and piperidine has a boiling point of106慰C.

  1. Explain the large difference (25慰C) in boiling point for these two isomers.
  2. Tetrahydropyran has a boiling point of 88慰C, and cyclopentanol has a boiling point of 141慰C. These two isomers have a boiling point difference of 53慰C.Explain why the two oxygen-containing isomers have a much larger boiling point difference than two amine isomers.
  3. N,N-Dimethylformamide has a boiling point of 150慰C, and N-methylacetamide has a boiling point of 206慰C, for a difference of 56慰C.Explain why these two nitrogen-containing isomers have a much larger boiling point difference than the two amine isomers. Also explain why these two amides have higher boiling points than any of the other four compounds shown (two amines, an ether, and an alcohol).

The preceding equation for the protonation of acetamide shows a hypothetical product that is not actually formed. When acetamide is protonated by a strong enough acid, it does not protonate on nitrogen, but at different basic site. Draw the structure of the actual conjugate acid of acetamide, and explain (resonance) why protonation occurs where it does rather than on nitrogen. Calculate the pKa of this conjugate acid.
