What trends are there in odour and flammability of alkanes when relating to molecular weight?
Hmm… the larger the weight the lower the flammability… because larger molecular weight requires more energy to excite the atoms… so you need to burn it more before it goes boom.
Methane explosion should be more flammable than octane ones, but octane ones pack more energy because it simply breaks down to more methane and more boom.
To confirm what I say, you should look for boiling points or flash points for just methane and octane, and the one with lower flash point or boiling point should be the more flammable one.
