(a) Interpretation: The fragmentation mechanisms for the observation of strong peak at m / z = 74 in EI mass spectrum of 2-methylpentanoic acid is to be stated. Concept introduction: The EI mass spectrum is one of the types of mass spectrum in which an organic compound is vaporized and is analyzed by the bombardment with high energy electrons. When high energy passes by the molecule, it ejects an electron. The molecule results in the formation of the radical cation. This radical cation is then fragmented into small pieces. The rate of fragmentation depends upon the stability of the radical cation.

The base peak in the mass spectrum of 2,2,5,5-tetramethylhexane (molecular mass = 142) is at m/z = 57, which corresponds to a composition of C4H9. Suggest a structure for the fragment that accounts for this peak and offer a reason for why this fragment is so abundant.

3b. 2-Methylhexane shows an intense peak in the mass spectrum at m/z = 85, 57 and 43. Propose the possible structures for these fragments.

The mass spectrum of 2,2-dimethylpropane shows only a very weak molecular ion peak at m/z = 72. However, a large peak at m/z = 57 is seen. Suggest a possible structure of the fragment giving rise to this large peak and suggest a reason as to why this peak is so large.
