Alkanes are also referred to as saturated hydrocarbons. Explain the meaning of the term hydrocarbon. Why are alkanes called saturated hydrocarbons?

Draw skeletal structures for each of the following molecules:

(b) cis-1-chloro-3-methylcyclohexane

Using condensed structural formulas, draw three conformers of hexane.

Draw a condensed structural formula and give the correct IUPAC name for the three alkane structural isomers with the molecular formula C₅H₁₂ .

Using wedge-and-dash bonds, draw a cis and a trans stereoisomers for each of the following compounds:

(b) 1-bromo-2-ethylcyclopentane

Using wedge-and-dash bonds, draw both the cis and trans stereoisomers for each of the following compounds:

(b) 1,3-diethylcyclobutane

For each of the following compounds, indicate whether or not it can exist as cis–trans stereoisomers. If it can exist as the two isomers, draw both as a condensed structure.

(a) H₂C=CHCH₂CH₃

For each of the following compounds, indicate whether or not it can exist as cis–trans stereoisomers. If it can exist as the two isomers, draw both as a condensed structure.
