Saturated vs. Unsaturated Hydrocarbons Examples

📚 Quick Study Guide

• 🍎 Hydrocarbons: Organic compounds containing only carbon and hydrogen.
• 🔗 Saturated Hydrocarbons (Alkanes):
  • 🔥 Contain only single bonds.
  • 🧪 General formula: $C_nH_{2n+2}$
  • ✨ Examples: Methane ($CH_4$), Ethane ($C_2H_6$).
• 🔗 Unsaturated Hydrocarbons:
  • 🔥 Contain at least one multiple bond (double or triple).
  • ✨ Alkenes: Contain at least one double bond. General formula: $C_nH_{2n}$. Example: Ethene ($C_2H_4$).
  • ✨ Alkynes: Contain at least one triple bond. General formula: $C_nH_{2n-2}$. Example: Ethyne ($C_2H_2$).
• 💡 Key Difference: Saturation refers to the maximum number of hydrogen atoms bonded to carbon. Unsaturated compounds can accommodate more hydrogen atoms if the multiple bonds are broken.
