Hydrocarbons are the fundamental family of molecules studied in the field of organic chemistry.
Organic chemistry is the study of carbon-based molecules. In the process of overlapping, the orbitals are distorted. Another way of describing what happens when orbitals overlap is to state that the orbitals combine to form a new type of orbital, called a hybrid. This new orbital can be described as part s orbital, part p orbital. The amount of s and the amount of p can vary.
