How Organic Molecules Change

Organic chemistry is all about reactions—how molecules transform and combine!

Four Major Reaction Types

• Substitution: One atom or group swaps with another.
• Addition: Atoms add across double or triple bonds.
• Elimination: Atoms are removed, often creating double bonds.
• Rearrangement: The molecule's skeleton is shuffled.

Reaction Conditions

Many reactions need special conditions: heat, light, or catalysts.
