What element do organic molecules primarily contain?

• A. Oxygen
• B. Hydrogen
• C. Carbon
• D. Nitrogen

Answer: (C)

Organic molecules are primarily characterized by the presence of carbon atoms. Carbon is unique because it can form four covalent bonds with other atoms, allowing for the creation of complex and diverse structures that are essential for life. This versatility enables carbon to bond with a variety of other elements, including hydrogen, oxygen, nitrogen, and various functional groups, leading to the vast array of organic compounds found in living organisms. While hydrogen is also a significant component of organic molecules, it typically accompanies carbon in these compounds, but it is carbon that is the backbone of organic chemistry. Other elements, like oxygen and nitrogen, are important in certain organic molecules, but without carbon, a molecule cannot be classified as organic. Thus, the defining characteristic of organic molecules is their carbon content.
