A new effect in the hot hydrogen displacement of halogen atoms from halomethanes is reported. Its interpretation involves recognition of factors that appear to control hot atom substitution of heavy atoms and groups. High kinetic energy (hot) hydrogen in the form of tritium recoiling from the He ³ (n,p)T nuclear process was allowed to react with the various fluoro-, chloro-, and bromomethanes. While replacement of F by T is quite probable in CH₃F, it is much less so in CH₂F₂, and almost nonexistent in in CHF₃ and in CF₄. By contrast replacement of H by T changes much less within this series. Exactly paralled trends appear in the chloro- and bromomethanes.
