One compound is revealed to be a hydrocarbon. What must the difference be with the other compound for there to be such a difference in boiling point? Of an alkene carbon?

Of an alkane carbon? Determine whether they are identical, completely different, or merely conformers of one another. Sketch a five-membered ring and give the bond-line structure, then compare it to a straight-chain hydrocarbon with five carbons to confirm whether there are more hydrogens in the ring or straight chain. Write the mathematical formula for the ratio of carbon to hydrogen for each compound to determine the pattern.

Sketch the skeletal structure for 3,4-dipropyl-2,5-dimethylethylbenzene. Is the substitution a 1,2- a 1,3- or a 1,4-? Examine their structures in order to answer the related questions. Which of the two fits this numerical scheme?

Hint: Toluene is a special name for benzene whose primary functional group is a methyl group substituted in place of one of its hydrogens. It ignites readily and burns readily. The substance is insoluble in water and floats on the surface. Is the substance likely to be organic or inorganic?
