Jul 30, 2014 · The mechanism for the Sn\HCl reduction involves reductive electron transfer of the nitro group while the tin is being oxidized. This diagram shows the electron transfers involved. …

Aug 2, 2018 · Hydrogenation of aromatic nitro groups (over, for example, $\ce{Pd/C}$) usually results in reduction to the corresponding aniline and is probably easier to carry out and work …

Aug 28, 2014 · I am trying to understand this mechanism for nitrobenzene reduction with $\ce{Sn/HCl}$. I do not understand why it implies that you pull off the $\ce{C-H}$ hydrogen …

\begin{aligned}\ce{ HCl + SnCl2 &-> SnCl\\ HCl + KMnO4 &-> MnCl2 + KCl + H2O }\end{aligned} If we look at the oxidation states of our reactants, and products, $\ce{H}$ has +1, $\ce{Cl}$ -1, …

Sep 29, 2022 · The std electrode potential for Sn/Sn(II) is -0.14, the std electrode potential for 2H+/H2 is 0 (by definition) so the reaction of Sn + 2H+ to Sn(II) + H2 is energetically …

Dec 4, 2019 · $\ce{HCl}$ is added to the nitrile group to give the imidoyl chloride salt first, which is then reduced by the tin(II) chloride. The initial product is the complex with $\ce{SnCl4}$ (which …

Oct 10, 2018 · For tin/HCl the reduction proceeds as a series of one-electron transfers from metal surface mixed with protonation. It seems that the lowest free orbital in the compound belongs …

Mar 8, 2019 · The book's reasoning is correct. Fe/HCl gives $\ce{FeCl2}$ on reaction and it gets hydrolyzed by steam vapors to produces more hydrochloric acid and hydrogen to push the …

Jul 23, 2021 · It is quickly hydrolyzed according to : $$\ce{SnCl2 + 2 H2O -> Sn(OH)2 + 2 HCl}$$ and $\ce{Sn(OH)2}$ is insoluble in water. To dissolve $\ce{SnCl2}$, this reaction has to be …

Mar 8, 2020 · Also, in case of 1,3- dinitrobenzene, $\ce{Sn + HCl}$ converts both the $\ce{-NO2}$ groups to $\ce{-NH2}$ groups. Now if we use $\ce{NH4HS}$ or some other nitrogen and …
