MS gives molecular weight (M⁺) and fragment clues. High-yield: isotope patterns for Cl/Br, base peak vs molecular ion, and common cleavage rules.
Reaction: Mass Spectrometry Basics — Molecular Ion, Isotopes, Fragments
What it does: MS gives molecular weight (M⁺) and fragment clues. High-yield: isotope patterns for Cl/Br, base peak vs molecular ion, and common cleavage rules.
Typical reagents: EI-MS (analysis)
Key intermediate: Varies / context-dependent
Driving force: Relief of ring strain / formation of stronger bonds
