Inorganic vs Organic Compounds

This lesson introduces organic and inorganic compounds, highlighting their differences. Organic compounds contain carbon and hydrogen, are larger due to carbon's bonding ability, and are non-electrolytes. Inorganic compounds, like carbon dioxide, are smaller, dissociate in water, and form electrolytes. The four major classes of organic compounds are carbohydrates, proteins, lipids, and nucleic acids. Inorganic compounds crucial for the human body include water, oxygen, carbon dioxide, and salts. The lesson emphasizes the relevance of these compounds to human anatomy and physiology.

What is a key characteristic that distinguishes organic compounds from inorganic ones?

• Presence of hydrogen
