A general rule for hydrocarbons is that the higher the molecular weight, the less flammable the hydrocarbon is.
Using this fact, arrange the following hydrocarbons in order of increasing flammability:
C4H8, C10H12, C2H4, C8H18
A.C2H4 = C4H8 < C10H12 < C8H18
B.C2H4 < C4H8 < C10H12 < C8H18
C.C2H4 < C4H8 < C8H18 < C10H12
D.None of the above are correct.
