Chapter 22: Problem 30

Give the structure for each of the following. a. 4-methyl-1-pentyne b. 2,3,3-trimethyl-1-hexene c. 3-ethyl-4-decene

Short Answer

Expert verified
a. Structure: \(CH_3-C≡C-CH_2-CH(CH_3)_2\) b. Structure: \(CH_2=CH-CH(CH_3)-C(CH_3)_2-CH_2-CH_3\) c. Structure: \(CH_3-CH_2-CH(CH_2-CH_3)-CH_2-CH=CH-CH_2-CH_2-CH_2-CH_3\)

Step by step solution

01

Main chain: 5 carbon alkyne

The main chain contains 5 carbons (pent-), and it has an alkyne (triple bond) at carbon number 1 (-yne). 2. Add the substituents
02

Add methyl group at C4

Add the methyl group (-CH3) to the 4th carbon of the main chain to get the final structure. Structure: \[CH_3-C≡C-CH_2-CH(CH_3)_2\] b. 2,3,3-trimethyl-1-hexene 1. Identify the main chain
03

Main chain: 6 carbon alkene

The main chain contains 6 carbons (hex-), and it has an alkene (double bond) at carbon number 1 (-ene). 2. Add the substituents
04

Add trimethyl groups at C2, C3, C3

Add three methyl groups (-CH3) to the 2nd carbon, and the other two to the 3rd carbon of the main chain to get the final structure. Structure: \[CH_2=CH-CH(CH_3)-C(CH_3)_2-CH_2-CH_3\] c. 3-ethyl-4-decene 1. Identify the main chain
05

Main chain: 10 carbon alkene

The main chain contains 10 carbons (dec-) and it has an alkene (double bond) at carbon number 4 (-ene). 2. Add the substituents
06

Add ethyl group at C3

Add ethyl group (-CH2CH3) to the 3rd carbon of the main chain to get the final structure. Structure: \[CH_3-CH_2-CH(CH_2-CH_3)-CH_2-CH=CH-CH_2-CH_2-CH_2-CH_3\]

Draw a structural formula for each of the following compounds. $$ \begin{array}{ll}{\text { a. } 2,2-\text { dimethylheptane }} & {\text { c. } 3,3 \text { -dimethylheptane }} \\ {\text { b. } 2,3 \text { -dimethylheptane }} & {\text { d. } 2,4 \text { -dimethylheptane }}\end{array} $$

There are three isomers of dichlorobenzene, one of which has now replaced naphthalene as the main constituent of mothballs. a. Identify the ortho, the meta, and the para isomers of dichlorobenzene. b. Predict the number of isomers for trichlorobenzene. c. It turns out that the presence of one chlorine atom on a benzene ring will cause the next substituent to add ortho or para to the first chlorine atom on the benzene ring. What does this tell you about the synthesis of m-dichlorobenzene? d. Which of the isomers of trichlorobenzene will be the hardest to prepare?

Cis-trans isomerism is also possible in molecules with rings. Draw the cis and trans isomers of \(1,2\) -dimethylcyclohexane. In Exercise \(43,\) you drew all of the noncyclic structural and geometrical isomers of $\mathrm{C}_{4} \mathrm{H}_{7} \mathrm{F}$ . Now draw the cyclic structural and geometrical isomers of \(\mathrm{C}_{4} \mathrm{H}_{7} \mathrm{F}\) .

Oxygen is carried from the lungs to tissues by the protein hemoglobin in red blood cells. Sickle cell anemia is a disease resulting from abnormal hemoglobin molecules in which a valine is substituted for a single glutamic acid in normal hemoglobin. How might this substitution affect the structure of hemoglobin?

In general terms, what does the secondary structure of a protein represent? How is the secondary structure of a protein related to its function?
