Draw structures for a saturated hydrocarbon that has a molecular ion with an m/z value of 128.
16. The peak with the greatest m/z value for alcohols is given by m/z M-18, where M represents
the molecular weight of the alcohols. The number 18 in "M-18" means that the radical cation
loses a (an)
molecule.
A
Carbon dioxide, CO2
В
Ethene, C2H4
C
Water, H20
Carbon monoxide, CO
Which of the following molecules will have a base
peak at (M – 43)
