Some technical differences between true lizards (Order Squamata) and alligators and crocodiles (Order Crocodilia) is that the true lizards have bony eye rings; no secondary palates (except a few skink species); and overlapping scales. Crocodilians have no bony eye ring, a bony secondary palate, and bony scutes without overlapping scales. There are many others, but these are some of the most significant.

They're both under the class Reptilia, but alligators, crocodiles, and caimans are in the Order Crocodilia, and lizards are in the order Squamata along with snakes and worm lizards.
