At school, we are taught that in bromine water, the following equilibrium is present: B r X 2 + H X 2 O ⇌ B r O H + H B r. Therefore, when you add an alkene to bromine water, you don't get bromination, but rather the B r O H reacts instead and you get the following reaction (lets say for ethene for example): C X 2 H X 4 + B r O H C X 2 H X ... how many fringes are on the tallitWebNo, because for ethene, $\mathrm{p}K_\text{a} = 44$. You won't be able to abstract even one proton. Maybe, you were thinking in ethyne ($\ce{HC#CH})$? In that case, you are right! The bis-alkylation would work with sodium amide as a base! But is the simultaneous abstraction of both protons the most plausible reaction then? how many frogs are there in minecraft
