Indeed, according to the Evans p K a table the cyclopropane C − H bond ( p K a ≈ 46) is more acidic than the C − H bond on the central carbon in propane ( p K a ≈ 51). We know that, in general, the acidity of C − H bonds follows the order s p > s p 2 > s p 3. This is because the more s -character in an orbital, the more ... florence bareyre
