6. Draw the reactants and draw and name the possible products for the following
reactions(if there are more then one possible set of products name at least two):

Methane + Ethane → propane
Octane → ethane + hexane
8. Explain why smaller hydrocarbons are distilled off higher in the fractionating
column then the larger ones.
