Rate constants for scavenging solvated electrons, ea", mostly in the range ke-< 108 M"1 s"1, have been measured in ethanol and, as needed for comparison, in water. There is a tendency for feCs-to equal fce>q-over a 103-fold range, but there are instances where ke-is much greater. Inefficient scavengers for ea" provide relatively efficient traps for dry electrons e' with 37% survival often at C37 ^1M scavenger but also as low as ~0.2 M. The outstanding exceptions are olefins for which k< 107 M"1 s"1, but they do not measurably react with e". Negative ion resonances for alkenes as large as 2.2 eV have been reported and neither e" nor ea" is expected to react. It is proposed that ea" is C2H5OH" and eaq~i s H20". The radical anions may transfer either e" or H to appropriate acceptors, the latter accounting for possible reaction of ea" with olefins and alkenols. The reaction eaq" + eaq" = H2 is explained in terms of H20~. Whenever e" and ea" produce a common electron adduct S", and an equilibrium es" + S ^S" is approximated, then C3-"1 is proportional to ke~.
