2017年4月30日 · $\begingroup$ @K.T. I am not quite sure about the mechanism here, but my best guess is actually that it is a mixture of both: The hydroxyl ions from dissociated …

2017年7月25日 · Aluminum chloride is very soluble in water, according to wikipedia 44-49g/100ml water depending on the temperature, so you shouldn't expect any preciptation.

2022年1月22日 · $\begingroup$ For the purpose learning organic chemistry, the point to retain should be: water (or, any molecule with an $\ce{-OH}$ group) reacts with the Lewis acid …

2020年4月28日 · $\ce{AlCl3(s) + aq → [Al(H2O)6]^{3+}(aq) + 3 Cl -(aq) }$ This is followed by an acidic hydrolysis paralleling transition metals : The hexaqua complex ion behaves exactly like …

2019年3月22日 · $\ce{2 Al(s) + 3 CuCl2 . 2 H2O (aq) → 3 Cu (s) + 2 AlCl3 (aq) + 6 H2O (l)}$ If we began the experiment with 0.99 g of Al, according to the stoichiometry of the reaction how …

Please note that this is 4-phenylbutanoyl chloride: My guess was that another molecule of 4-phenylbutanoyl chloride would react with the phenyl, thus forming a structure like the one …

2021年8月15日 · $\begingroup$ @TooTea The purpose of $\ce{AlCl3}$ is to act as a Lewis acid catalyst. Depending on the electron density of the aromatic system (Lewis basicity), the group …

2022年4月25日 · Can concentrated strong acid like H₂SO₄ be used to protonate a carboxylic acid to RC(OH)₂⁺, forming RCO⁺ by removal of H₂O, analogous to the reaction with nitric acid to …

2017年10月14日 · I have noticed (during an experiment) that the boiling point of the solutions created by H2O+KBr; H2O+CaCl2 and H2O+AlCl3 see their boiling point increase. During the …

2014年9月4日 · $\begingroup$ @Dissenter It means that the $\ce{H2O}$ isn't really generated from the reaction, but exists already. You added a $\ce{H2O}$ in the second step. …
