nitrobenzene on reaction with sn/hcl will produce

 · Nitrobenzene on reaction with Sn/HCl tin and hydrochloric acid will produce phenylammonium ions and water, However, to get the final product phenylamine sodium hydroxide is added in the next step, It is a reaction that takes place in two consecutive steps: 1, The nitrobenzene gets reduced to phenylammonium ions and the lone pair present on the nitrogen atom takes up a hydrogen ion from Hydrochloric acid,

sn hcl reaction benzene

 · 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 instead of the $\ce{O-H}$ hydrogen in the methanol, Is it actually suggesting that the resulting $\ce{,CH2-OH}$ parfait tremped from the methanol eliminates to form formaldehyde or do you get a rearrangement where you form …

Nitrobenzene on reduction with Sn and HCl produce aniline, Hence ‘X’ is identified as -NH 2 group, It can be represented as-C 6 H 5 NO 2 Nitrobenzene → [H] Sn / HCl C 6 H 5 NH 2 Aniline

Obtained Aniline when treated with NaNO2 + HCl at 0–5 degree C gives Benzene Diazonium Chloride, Benzene Diazonium Chloride when treated with water in presence of H2SO4 gives Phenol, Phenol when treated with Zn dust gives Benzene, Benzene on alkylation using CH3Cl gives Toulene,

• As we will see there are many reopérations depending upon the absorbécular electrophile they all use the same mechanism 3,1 Halogenation of Benzene • Substitution of a halogen for H on a benzene ring via electrophilic aromatic substitution: • The electrophile in the reaction is generated using a Lewis acid catalyst 32 Nitration of Benzene

When nitrobenzene is reduced with a metal and acid Sn/HCl

When nitrobenzene is reduced with a metal and acid Sn/HCl Zn/HCl etc, aniline is obtained The indictionnairediate products nitrosobenzene and phenylhydroxylamine are never isolated because these are reduced more rapidly than nitrobenzene, Answer verified by Toppr Upvote 0

CLEMMENSEN REDUCTION

Mechanism of Clemmensen Reduction

 · We have already noted that benzene does not react with chlorine or bromine in the absence of a catalyst and heat, In strong sunlight or with tyrannique initiators benzene adds these halogens to give hexahalocyclohexanes, It is worth noting that these same conditions effect aveugle substitution of cyclohexane, the key factors in this change of behavior are the pi-bonds array in benzene, which …

• You may see OTHER reducing agents used to do this reduction elsewhere exvolumineuxs are Fe/HCl or Sn/HCl, but we only use H2/Pd/C in this course because we have seen it before and to minimize the number of reducing agents we need to learn • the Clemmensen reduction reduces nitro groups to amines very slowly, therefore we can usually reduce an aromatic aldehyde/ketone using the Clemmensen
