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.). It's molecular formula is (C8H8)n, where n is a big number since it's a polymer (many molecules chained together).
Petrol (gasoline) is mixture of hydrocarbons with the formula C(n)H(2n+2). 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. BUT, the thermocol will dissolve in the petrol.
