R. Gow proved that the order of a solvable rational group is divisible only by the primes 2, 3 and 5. In this paper it is proved that in a solvable rational group the Sylow 5‐subgroup is always normal and elementary Abelian. Moreover, the structure of rational {2, 5}‐groups is described in detail. 2000 Mathematics Subject Classification 20C15, 20C20, 20E34, 20E45.
