Cracking

Definition

Cracking is a process in organic chemistry where complex organic molecules, particularly long-chain hydrocarbons, are broken down into simpler molecules by breaking carbon-carbon bonds. This process is essential in converting heavy fractions of petroleum into more useful products like gasoline and diesel.
