Exploring Hydrocarbons and Functional Groups

Define aromatic hydrocarbons and give an example.

• Cyclohexane (C6H12)

• Benzene (C6H6)

• Ethylene (C2H4)

• Toluene (C7H8)

Explain the significance of functional groups in organic chemistry.

• Functional groups are irrelevant in determining compound stability.

• Functional groups are significant in organic chemistry because they determine the chemical properties and reactivity of organic compounds.

• Functional groups only affect the physical state of a compound.

• Functional groups are solely responsible for the color of organic compounds.

What is the difference between primary, secondary, and tertiary alcohols?

• Tertiary alcohols have one carbon attached to the -OH carbon.

• Primary alcohols have two carbons attached to the -OH carbon.

• Secondary alcohols have three carbons attached to the -OH carbon.

• Primary alcohols have one carbon attached to the -OH carbon, secondary alcohols have two, and tertiary alcohols have three.
