What is the Difference Between Organic and Inorganic Molecules?

🆚 Go to Comparative Table 🆚

The main difference between organic and inorganic molecules lies in their origin, chemical properties, elemental composition, and bonds. Here are the key differences:

  1. Origin: Organic molecules are derived from or produced by living organisms, while inorganic molecules are obtained from nonliving sources, such as minerals and metals.
  2. Carbon content: Organic molecules contain carbon-hydrogen (C-H) bonds, while most inorganic molecules do not contain carbon atoms, with some exceptions.
  3. Chemical properties: Organic compounds are generally more complex and have carbon-hydrogen bonds, whereas inorganic compounds are generally simpler and have ionic bonds.

Examples of organic compounds include urea, ATP, ethanol, and cholesterol. Examples of inorganic compounds include ammonia, sodium chloride, potassium bromide, and calcium chloride.

Comparative Table: Organic vs Inorganic Molecules

The main difference between organic and inorganic molecules lies in their composition, origin, and chemical properties. Here is a table comparing the two types of molecules:

Property Organic Molecules Inorganic Molecules
Origin Derived from or produced by living organisms Derived from nonliving components
Carbon-Hydrogen Bonds Contain carbon-hydrogen (C-H) bonds Lack carbon-hydrogen bonds, but may contain carbon atoms
Examples Urea, ATP, ethanol, and cholesterol Ammonia, sodium chloride, potassium bromide, and calcium chloride
Elemental Composition Contain carbon, hydrogen, and sometimes additional elements (e.g., oxygen, nitrogen, and sulfur) Primarily consist of elements other than carbon and hydrogen
Bonding Form covalent bonds Form ionic bonds between atoms of molecules
Aqueous Solutions Poor conductors of heat and electricity Good conductors of heat and electricity
Examples Fats, nucleic acids, sugars, enzymes, proteins, and hydrocarbon fuels Non-metals, salts, metals, acids, bases, substances made from single elements

Organic molecules are derived from or produced by living organisms and contain carbon-hydrogen covalent bonds, while inorganic molecules are derived from nonliving components and generally have ionic bonds. Organic molecules are primarily composed of carbon, hydrogen, and sometimes additional elements like oxygen, nitrogen, and sulfur, whereas inorganic molecules primarily consist of elements other than carbon and hydrogen.
