Organic chemistry is the study of carbon compounts and it encompasses all molecules that contain carbon. The nature of the carbon atom allows it to form a wide variety of molecules, from very simple ones like methanol that contains just a single carbon to incredibly complex molecules like phospholipids that form chains that can be over 20 carbons long. What type of bond does carbon most commonly form with other atoms?
A. ionic bonds
B. hydrogen bonds
C. carbon bonds
D. covalent bonds
