Chapter 25: Problem 45

Draw the condensed structure of the compounds formed by condensation reactions between (a) benzoic acid and ethanol, (b) ethanoic acid and methylamine, (c) acetic acid and phenol. Name the compound in each case.

Short Answer

Expert verified
The condensed structures of the compounds formed by condensation reactions are: (a) Benzoic acid and ethanol react to form ethyl benzoate with the structure \[C_6H_5COOCH_2CH_3\]. (b) Ethanoic acid and methylamine react to form N-Methyl ethanamide with the structure \[CH_3CONHCH_3\]. (c) Acetic acid and phenol react to form phenyl acetate with the structure \[CH_3COOC_6H_5\].

Step by step solution

01

(a) Benzoic acid and ethanol

The reacting functional groups in these compounds are the carboxyl group (COOH) in benzoic acid and the hydroxyl group (OH) in ethanol. In a condensation reaction, these groups combine, with the elimination of a water molecule. Benzoic acid: \[C_6H_5COOH\] Ethanol: \[CH_3CH_2OH\] On combining, the product formed is an ester with the structure \[C_6H_5COOCH_2CH_3\]. This ester will be named by localizing the alkyl group on the alcohol first and then the carboxyl group on the acid. Hence, the name of the compound: Ethyl benzoate.
02

(b) Ethanoic acid and methylamine

The reacting functional groups in these compounds are the carboxyl group (COOH) in ethanoic acid and the amine group (NH2) in methylamine. Again, during the condensation reaction, these groups combine and a water molecule is eliminated. Ethanoic acid: \[CH_3COOH\] Methylamine: \[CH_3NH_2\] On combining, the product formed is an amide with the structure \[CH_3CONHCH_3\]. The amide will be named by replacing the "oic acid" of the acid with "amide" and putting the alkyl group of the amine in front. Hence, the name of the compound: N-Methyl ethanamide.
03

(c) Acetic acid and phenol

The reacting functional groups are the carboxyl group (COOH) in acetic acid and the hydroxyl group (OH) in phenol. They combine in a condensation reaction, eliminating a water molecule. Acetic acid: \[CH_3COOH\] Phenol: \[C_6H_5OH\] On combining, the product formed is an ester with the structure \[CH_3COOC_6H_5\]. This ester will be named by localizing the alkyl group on the alcohol first, and then the carboxyl group on the acid. Hence, the name of the compound: Phenyl acetate.

Draw the condensed structures of the compounds formed from (a) butanoic acid and methanol, (b) benzoic acid and 2 -propanol, (c) propanoic acid and dimethylamine. Name the compound in each case.

(a) Describe the primary, secondary, and tertiary structures of proteins. (b) Quaternary structures of proteins arise if two or more smaller polypeptides or proteins associate with each other to make an overall much larger protein structure. The association is due to the same hydrogen bonding, electrostatic, and dispersion forces we have seen before. Hemoglobin, the protein used to transport oxygen molecules in our blood, is an example of a protein that has quaternary structure. Hemoglobin is a tetramer; it is made of four smaller polypeptides, two "alphas" and two "betas." (These names do not imply anything about the number of alpha helices or beta sheets in the individual polypeptides.) What kind of experiments would provide sound evidence that hemoglobin exists as a tetramer and not as one enormous polypeptide chain? You may need to look into the chemical literature to discover techniques that chemists and biochemists use to make these decisions.

(a) What is an \(\alpha\) -amino acid? (b) How do amino acids react to form proteins? (c) Draw the bond that links amino acids together in proteins. What is this called?

Write the structural formulas for as many alcohols as you can think of thathave empirical formula \(\mathrm{C}_{3} \mathrm{H}_{6} \mathrm{O}\).

Write the condensed structural formula for each of the following compounds: (a) 2 -pentanol, (b) 1,2 propanediol, (c) ethyl acetate, (d) diphenyl ketone, (e) methyl ethyl ether.
