(a) Interpretation: The structures of the species that correspond to each of the peaks A–E in the given mass spectrum of heptane is to be drawn. Concept introduction: The mass spectrum of a compound is often represented as a bar graph with m/z on the x axis (where m is in atomic mass units, u) and the relative abundance of ions at each m/z on the y axis. The mass of each ion is just the mass of the atoms that make it up. The M + peak of a mass spectrum is taken to be the compound’s molecular mass. Each fragmentation produces a cation and an uncharged species, ensuring that the total charge after fragmentation is the same as it was before fragmentation. When a molecular ion undergoes fragmentation, there must be conservation of charge. A molecular ion whose charge is +1 invariably fragments into one species bearing a +1 charge and another that is uncharged.

Q9. The insecticide DDT (in the box below) is useful in controlling mosquito populations and has low toxicity to humans, but is dangerous to birds and fish. Hoping to alleviate the dangers, little Johnny Whizbang, an aspiring chemist, proposes a new version of DDT ("Bromo-DDT") and shows his synthesis to his boss. Will Johnny Whizbang's synthesis work? Or will he be fired? Assume there is an excess of bromine and polybrominated products can be separated. Explain why.
