Abstract :
We study finite groups with rational valued non-linear characters and obtain the structureof these types of groups with derived subgroup of prime order. In particular, in the case ofthe size of derived subgroup of a group is two we conclude that this group is rational if andonly if the group is a direct product of an extraspecial 2-group with an elementary abelian2-group.
