Problem 23
What is the final product of the double elimination of HCl from 1,1-dichloroethane?
Problem 24
Draw the structure of the final product of the double elimination of 1,3-dibromopropane.
Problem 27
Draw the smallest molecule that can have a separate aldehyde and carboxylic acid group.
Problem 29
Ethyl acetate is a common ingredient in nail-polish remover because it is a good solvent. Draw the structure of ethyl acetate.
Problem 30
30\. A lactone is an ester that has its ester functional group in a ring. Draw the structure of the smallest possible lactone. (It is called acetolactone, which might give you a hint about its structure.)
Problem 31
Draw the structure of diethyl ether, once used as an anesthetic.
Problem 32
The smallest cyclic ether is called an epoxide. Draw its structure.
Problem 33
Write the chemical reaction of \(\mathrm{HCl}\) with trimethylamine.
Problem 34
Putrescine and cadaverine are molecules with two amine groups on the opposite ends of a butane backbone and a pentane backbone, respectively. They are both emitted by rotting corpses. Draw their structures and determine their molecular formulas.
Problem 35
With four monomers, draw two possible structures of a copolymer composed of ethylene and propylene.
