Chapter 22: Problem 30

Cumene is the starting material for the industrial production of acetone and phenol. The structure of cumene is Give the systematic name for cumene.

Short Answer

Expert verified
The systematic name for cumene is 2-Methyl-3-phenylhexane.

Step by step solution

01

Identify the parent chain

Find the longest continuous chain of carbon atoms in cumene molecule. This chain will act as the basis for the systematic name of the compound.
02

Identify the substituents

Examine the structure of cumene for any additional atoms or groups attached to the parent chain. These substituents will be included in the systematic name.
03

Number the carbon atoms

Assign numbers to the carbon atoms in the parent chain, starting from the end nearest to the substituent. The numbers help in identifying the position of the substituents in the molecule.
04

Construct the systematic name

Combine the information obtained from the previous steps to construct the systematic name for cumene, following the IUPAC naming rules. ![Cumene Structure](https://upload.wikimedia.org/wikipedia/commons/thumb/0/0d/Cumene_str.png/1280px-Cumene_str.png) Looking at the structure of cumene, we can identify: - Parent chain: A 6-carbon chain (hexane) - Substituent: A methyl group (-CH3) at position 2 - Substituent: A phenyl group (C6H5) at position 3 (connected to the 3rd carbon atom of the parent chain) Combining this information, we construct the systematic name: 2-Methyl-3-phenylhexane

Polycarbonates are a class of thermoplastic polymers that are used in the plastic lenses of eyeglasses and in the shells of bicycle helmets. A polycarbonate is made from the reaction of bisphenol A (BPA) with phosgene \(\left(\mathrm{COCl}_{2}\right)\) : polycarbonate \(+2 n \mathrm{HCl}\) Phenol \(\left(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{OH}\right)\) is used to terminate the polymer (stop its growth). a. Draw the structure of the polycarbonate chain formed from the above reaction. b. Is this reaction a condensation or an addition polymerization?

Draw all the structural and geometrical (cis-trans) isomers of \(\mathrm{C}_{3} \mathrm{H}_{5} \mathrm{Cl} .\)

What is wrong with the following names? Give the correct name for each compound. a. 2 -ethylpropane b. 5 -iodo \(-5,6\) -dimethylhexane c. cis-4-methyl-3-pentene d. 2 -bromo- 3 -butanol

Three different organic compounds have the formula \(\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}\). Only two of these isomers react with \(\mathrm{KMnO}_{4}\) (a strong oxidizing agent). What are the names of the products when these isomers react with excess \(\mathrm{KMnO}_{4}\) ?

Over 100 different kinds of mutant hemoglobin molecules have been detected in humans. Unlike sickle cell anemia (see Exercise 93), not all of these mutations are as serious. In one nonlethal mutation, glutamine substitutes for a single glutamic acid in normal hemoglobin. Rationalize why this substitution is nonlethal.
