We investigate the zero temperature chiral phase transition in an SU(N) gauge theory as the number of fermions Nf is varied. We argue that there exists a critical number of fermions Nfc, above which there is no chiral symmetry breaking or confinement, and below which both chiral symmetry breaking and confinement set in. We estimate Nfc and discuss the nature of the phase transition.
