Question

Why thermocol dissolves in petrol

Answer 1

Thermocol is made of polystyrene, which is a long chain of carbons that has a phenyl (benzene, C6H5) group coming attached to every other carbon (so on carbon 1,3,5 etc.). ... Usually the molecules have 8 carbons (or so), so we can just say its formula is C8H18. So when petrol and thermocol mix, no reaction happens
