Problem 3
Define hydrocarbon. What are the two general types of hydrocarbons? What are the three different types of aliphatic hydrocarbons? How are they defined? Indicate whether each molecule is an aliphatic or an aromatic hydrocarbon. If it is aliphatic, identify the molecule as an alkane, an alkene, or an alkyne.
Problem 4
Draw the bond-line structure of all noncyclic alkanes with only five \(\mathrm{C}\) atoms.
Problem 5
What is the difference between an addition polymer and a condensation polymer?
Problem 5
Cyclic alkanes can also have substituent groups on the ring. Draw the bond- line structure of all cyclic alkanes with only four \(\mathrm{C}\) atoms.
Problem 6
Cyclic alkanes can also have substituent groups on the ring. Draw the bond- line structure of all cyclic alkanes with only five \(\mathrm{C}\) atoms.
Problem 6
What is the difference between a condensation polymer and a copolymer?
Problem 7
Name and draw the structural formulas for the four smallest alkanes.
Problem 7
List three properties of polymers that vary widely with composition.
Problem 7
Draw and name all possible isomers of pentene.
Problem 8
Draw and name all possible normal (that is, straight-chain) isomers of heptyne.
