In the present work the electronic density of states of liquid, viz., Zintli alloys, have been studied only at the composition of their maximum resistivity to have an elementary idea about the behaviors of the alloys with respect to nearly free electron behavior. The study reveals that the anomalous electronic behavior of liquid Li-Pb, Na-Pb, Li-Sn, and Na-Sn can be attributed to the preferential ordering of unlike atoms.
