Chemistry: Cracking

HideShow resource information


The phenomenon in which large molecules of hydrocarbons are thermally decomposed into smaller molecules in the absence of air or oxygen is known as Cracking or Pyrolysis. 

Examples of Cracking

Cracking can be explained with the help of following examples. 

1. Methane 
When methane is burnt in absence of air then cracking takes place, as a result carbon black and hydrogen are formed. 

2. Gasoline 
The most
