Homework Statement


Hi,
consider hexene(C6H12) and cyclohexane(C6H12)
1:Are they isomers?
2:Do they produce the same amount of soot?


Homework Equations





The Attempt at a Solution


1:um....I have only learnt structural isomerism.
Are they functional group isomers?As they belong to different homologous series
(cycloalkanes and alkenes)..?
2:I am not sure.So far I only know that the C to H ratio affect the amount of soot produced.
The larger the C/H ratio,the more the soot produced.However, the C/H ratio in both compounds are equal,are there any other factors affecting the amount of soot given out in the combustion?

The word "isomer" has a definition and a meaning. Yes there are different kinds of isomers, but you have been asked whether they are isomers in general -- no particular type. So find the definition and check those two compounds.

Part (2) Do they produce the same amount of soot?

For any particular fuel, the amount of soot produced is not a constant -- it depends a great deal upon the exact reaction conditions. Were you given any particular conditions under which the fuel was to be burnt or thermally decomposed without air? Acetylene produces huge amounts of soot if you just throw calcium carbide into a puddle and light it up. It produces almost none if you are using an oxy-acetylene welder!

I guess the question aims at the difference between burning of alkanes and alkenes.
