The relative rates of electrophilic substitution of a number of series of metal alkysl of type RMXn(where X may = R), in which the alkyl group R varies along the series, have been interpreted in terms of the following mechanisms of substitution: (a) mechanism SE2, which results in a steric sequence of relative rate constants (R = Me > Et > Pr >iso-Pr >tert-Bu), (b) a newly-defined mechanisms SEC, which
