WebThe extra reactivity of cyclopropane. In the presence of UV light, cyclopropane will undergo substitution reactions with chlorine or bromine just like a non-cyclic alkane. However, it also has the ability to react in the dark. In the absence of UV light, cyclopropane can undergo addition reactions in which the ring is broken. WebThe Henry's Law constant for cyclopropane is estimated as 0.79 atm-cu m/mole(SRC) from its experimental values for vapor pressure, 5.4X10+3 …
WebFeb 4, 2024 · 1 Answer. 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 ...
