Scientific theory states that the atoms in today's plastics were parts of microscopic plants and animals that lived in the oceans millions of years ago. b. Molecules of gasoline have more carbon atoms than do molecules of diesel fuel. c. Subjecting large molecules to cracking is useful because smaller molecules are manipulated more easily in a reaction to produce a desired product. d. Unsaturated compounds form during hydrocarbon cracking because too many hydrogen atoms are available for the number of carbon atoms.
