C_nH_2n+2
What bonds are broken during cracking of alkanes?

C-C
What is thermal cracking?

Cracking of long chain molecules into shorter chain molecules by breaking the C-C bonds, thermal cracking takes place at high temperatures (up to 100'c) and high pressure (up to 70 atm). Produces alkenes.
In thermal cracking, what are the alkenes produced used for?
