Why wouldn't they? It should be the exact same material in the regular semester. Heck I did organic chem 2 in a 4 week summer half session, thought I should have gotten a medal after that one.
I took orgo 1 and 2 back to back in one summer at a different four year university that was closer to where I was living at the time rather than the main one I attended. Didn't have any issues with interviews/acceptances.
