3
In what order should branches be listed when naming alkenes?
Alphabetical order
Which property of alkenes allows them to dissolve in non-polar solvents?
Non-polarity
What type of isomerism occurs due to the presence of a double bond in alkenes?
Geometric isomerism
In a cis isomer, where are the two larger groups attached to the double bonded carbon atoms located?
On the same side of the double bond
What happens to the double bond during an addition reaction?
One bond breaks to form two new bonds
What type of compounds are alkenes classified as?
Unsaturated compounds
Which of the following is NOT a common atom or group added to a double bond in an addition reaction?

How do the boiling points of alkenes generally compare to those of similar-sized alkanes?
Alkenes have lower boiling points
What is the role of ethene gas in ripening fruit?
It speeds up the ripening process
What happens to the alkene during an addition reaction?
It splits into two different groups
What happens to a symmetrical reactant when it adds to a multiple bond?
It remains symmetrical
Which of the following is an example of an asymmetrical alkene?

During fractional distillation, which hydrocarbons are removed first in the lower sections of the fractionation tower?
Lighter hydrocarbons
What is the main objective of fractional distillation in oil refineries?
To separate petroleum into its various hydrocarbon components
What process is used to break larger hydrocarbon molecules into smaller gasoline molecules?
Cracking
What is the primary purpose of reforming in the oil industry?
