Hydrocarbons and Their Reactions

What type of bonds are found in alkanes?

• Only single bonds

• Only double bonds

• Only triple bonds

• A mix of single and double bonds

What is the main difference between alkenes and alkynes?

• Alkenes have single bonds, alkynes have double bonds.

• Alkenes have double bonds, alkynes have triple bonds.

• Alkenes have triple bonds, alkynes have single bonds.

• Alkenes have more carbon atoms than alkynes.

A hydrocarbon with three carbon atoms and one double bond would be named:

• Propane

• Propyne

• Propene

• Butene

What describes cis-trans isomers?

• They have different numbers of atoms.

• They have the same structure but different orientations around a double bond.

• They can easily switch between cis and trans forms.

• They only occur in compounds with single bonds.

What happens during an addition reaction?

• Atoms are removed from a molecule.

• Atoms are added to carbons that had double bonds.

• Only single bonds are involved.

• Molecules are broken into smaller pieces.

Which type of fat is usually solid at room temperature and has no double bonds?

• Unsaturated fat

• Polyunsaturated fat

• Saturated fat

• Monounsaturated fat

What is the main goal of hydrogenation in making food products?

• To make fats less stable.

• To change saturated fats into unsaturated fats.

• To make unsaturated fats easy to spread and last longer.

• To remove all hydrogen from fat molecules.

Why are trans fats considered bad for your body?

• Your body can easily break them down.

• They are a type of saturated fat.

• Your body does not have good ways to break them down.

• They are found in many healthy foods.
