Understanding Alkenes

What is the suffix used for naming alkenes?

• -ane

• -yne

• -ol

• -ene

Why can't an alkene have only one carbon atom?

• Because it needs a single bond

• Because it needs a double bond

• Because it needs a quadruple bond

• Because it needs a triple bond

When drawing alkenes, why is it important to check the number of bonds each carbon has?

• To ensure each carbon has two bonds

• To ensure each carbon has five bonds

• To ensure each carbon has four bonds

• To ensure each carbon has three bonds

What prefix is used for an alkene with three carbon atoms?

• Eth-

• Prop-

• But-

• Pent-

How do you determine the numbering of carbon atoms in an alkene?

• By counting from the end with the most hydrogen atoms

• By counting from the end with the least hydrogen atoms

• By counting from the end closest to the double bond

• By counting from the end farthest from the double bond
