The vaporized oil rises up the column-the various fractions tap of different levels where they condense 11 of 14 Cracking Splitting up long-chain hydrocarbons 12 of 14 Thermal decomposition breaking molecules down by heating them 13 of 14 Alkenes have a c=c double bond-unsaturated because they can make more bonds. Double bonds can open up. 14 of 14
