Concept introduction:
The nuclear reactions are a type of chemical processes which lead to the formation of some new nuclei with the emission of certain particles. Usually alpha or beta particles, or gamma rays are emitted as a side product with some new daughter nuclei. The nuclei which shows spontaneous decay with time are called as radioactive nuclei. The radioactive decay follows the first order kinetic and the half-life is inversely proportional to the decay constant of the radioactive decay.

For each set of carbonyl additions, circle the carbonyl addition that occurs at the faster rate
(assuming everything is the same except that the reagent/substrate differs - i.e., same
temperature, and ratios/concentrations of reagent and substrate). Electrostatic attraction has
a greater impact on the relative rates than steric hindrance.

- 7. Our textbook says that the fragmentation that occurs in the mass spectrometry of alkanes can be understood by realizing that "the differences in energy among ... tertiary, secondary, primary and methyl carbocations in the gas phase are much greater than the differences among comparable radicals. Therefore, where alternative modes of fragmentation are possible, the more stable carbocation tends to form in preference to the more stable radical." Given this information, which one of the following hexane isomers (all C6H14) is most likely to have a strong M-15 peak (that is, a peak at m/z 71)?
