We review the large Nc behavior of light scalar and vector resonances generated from unitarized meson-meson scattering amplitudes at one loop in Chiral Perturbation Theory. The vectors nicely follow the behavior expected for qqbar states, whereas scalar mesons do not. This suggests that the main component of light scalars is not qqbar. We also comment on t-channel vector exchange as well as on the large Nc behavior of the mass splittings between the vectors generated from the inverse amplitude method.
