Question

what makes the dawn wall so difficult to free climb​

Answer 1

Explanation:

There are 17 pitches—half the route—rated 5.13 or harder. The fact that Yosemite's two hardest pitches, pitches 14 and 15, are located right in the middle of the Dawn Wall is what makes this route so challenging. It's safe to say that it'll be a long time before anyone repeats this rock climb.
