, 1. What are alkenes? Alkenes are organic compounds that contain a carbon-carbon double bond.
2. What are alkynes? Alkynes are organic compounds that contain a carbon-carbon triple bond.
3. What type of hydro- They are classified as unsaturated hydrocarbons because they contain fewer
carbons are alkenes than the maximum number of hydrogen atoms.

4. What is the general Saturated fatty acids have long carbon chains (12-20 carbon atoms) with no
structure of a satu- double bonds and are solid at room temperature.
rated fatty acid?
5. What is hydrogena- Hydrogenation is the addition of hydrogen (H₂) to an alkene, resulting in the
tion? formation of an alkane.
