🚀 Fun Fact: Did you know that the term "unsaturated" can also refer to a sponge that hasn't soaked up as much water as it could? In the world of chemistry, it means that our molecules can still bond with more atoms!

• Alkenes = compounds with a carbon-carbon double bond (like two people holding hands).
• Alkynes = compounds with a carbon-carbon triple bond (like three people holding hands).

🍿 Real-world Example: Think of alkenes and alkynes as hungry eaters. They love hydrogen. And they can "eat" or bond with more hydrogen to become "full" or "saturated".

• It's like turning a high-volume song down a notch. Alkenes and alkynes get "calmer".
• When you add hydrogen to them, they go from "hungry" to "full".
• Catalysts (like magic wands!) help speed up this process. For alkenes and alkynes, our star catalysts are metals like palladium (Pd), nickel (Ni), and platinum (Pt).
