N2 - The decomposition rate of chemically activated ethyltrimethylgermane from the reaction 1CH2 + (CH3)4Ge, where 1CH2 was produced from diazomethane photolysis at 3660 Å, is 8.6 × 105 sec−1. This result combined with RRKM theory and critical energy estimates yields an Arrhenius A factor of log[A (sec−1)/methyl] = 14.7 ± 0.8 for methyl rupture from germanium. Log A values for methyl rupture from carbon, silicon, and germanium linearly correlate with the vibrational‐rotational entropies of the corresponding tetramethyls. Extrapolation predicts log[A (sec−1)/methyl] = 14.4 and 14.3 for methyl rupture from tin and lead, respectively.
