Model 3: Ionization and Fragmentation Most mass spectrometers accelerate a molecule by first turning it into an ion, then using an electric field to accelerate it toward the detector. During standard ionization, a molecule loses one electron, the electron that is easiest to remove. The following is a hierarchy of electrons from easiest to hardest to remove: Electron in a lone pair (easiest) Electron that is part of a double bond (pi bond) Electron in a single bond (hardest) Knocking off an electron to make a +1 ion can be a harsh process. This harsh treatment often results in a broken bond, generating two smaller pieces, a +1 ion and a neutral fragment. (Note that only the ion is accelerated and detected.) ● 7. ● Critical Thinking Questions 6. If acetone is ionized, which electron is most likely to be knocked off? Replace this electron with a + (to indicate the missing electron) on the structure of acetone → The ion you drew above is called the "molecular ion" of acetone. It is…

i) ii) iii) d. Assign the following molecules as either E, Z or neither. Note: there may not be one of each. HO H₂C- Br O Br Br O Br Br -CH3

Please help! Rank the first two groups in order of SN1 sensitivity and the second group in order of SN2 sensitivity. Halide ranking advice appreciated

Predict and draw the major fragment structures and associated mass of each fragment for the following compounds.

Please examine both of these graphs (Infrared Spectroscopy, and Mass spectroscopy) and determine the bonds, structure, molecular formula and IHD of the unknown organic compound. Please also give reasoning as to why, an explanation would be great. Thank you very much.
