WebAnalysing and explaining the principal ions in the fragmentation pattern of the mass spectrum of cyclohexene. Atomic masses: H = 1; C = 12 (13 for ~1 in 100). Bond enthalpies = kJ/mol: C-C = 348; C-H = 412; C=C = 612. Possible equations to explain some of the most abundant ion peaks in the mass spectrum of cyclohexene (tabulated above) Cyclohexane is a cycloalkane with the molecular formula C6H12. Cyclohexane is non-polar. Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products (in which it is sometimes used). Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to nylon. Cyclohexyl (C6H11) is the alkyl substituent of cyclohexane and is abbreviated Cy.
