Hahaha yeah I wrote that too that smaller fractions are more useful than heavier ones . I read in the text book right now that alkenes are obtained from the cracking of alkanes so that could have been one of the answers but I didnt write in the exam :p The second point I wrote was to obtain hydrogen :p
Lol Even i wrote that smaller chains are more useful...but then i wrote that they are more easy to recycle :/

That's correct : well I wrote cracking produce : Alkene which are used for making polymers and 2) cracking produce alkane used as feed stock for *reforming (which is wrong i guess) and making petrol (this is right) ---so my last answer is neither right nor wrong

i said they are cracked into smaller hydrocarbons because large ones are really volatile..and less flammable so they are less usefull
