Pin oak has a smaller range. Here in NY its generally confined to the western Lake Plains and downstate near the City, so it may extend into CT, but I'm not sure.
Black oak tends to be more of a southern species. In NY it is more often found on the drier hillsides of the Finger Lakes region.
You can find species range maps @ Silvics Manual Volume 1-Conifers and Volume 2-Hardwoods
