  1. What is the general formula of an alkane?
    CnH2n+2
  2. What bonds are broken during cracking of alkanes?
    C-C
  3. 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.
  4. In thermal cracking, what are the alkenes produced used for?
    polymers
  5. What are the economical reasons for cracking?
    To produce molecules which are in short supply and high demand.
