The mass spectra of exo ‐2‐norbornyl chloride, 1‐ and 2‐methyl exo ‐2‐norbornyl, exo‐camphenilyl, apoisobornyl, bornyl and isobornyl chloride, and camphene hydrochloride, α‐ and β‐fenchyl chloride and fenchene hydrochloride, and exo ‐isofenchyl chloride and 2,5,5‐trimethyl exo ‐2‐norbornylchloride, and camphene and α‐fenchene have been examined at 12 to 16 and 80° eV and at 30 to 49 and 80°, or higher temperatures. Wagner‐Meerwein rearrangements occur very readily in the ion source and compounds related by these rearrangements give very similar fragmentation patterns. Thermal decompositions are important with the tertiary chlorides especially at higher source temperatures. The rates of methanolysis of some of these chlorides were measured.
