The structure of the compound formed, when nitrobenzene is reduced by lithium aluminium hydride (LiAlH4) is= A. … Since the nitro group contains polar double bonds, Lithium aluminum hydride reduces aromatic nitro compounds to azo products.
WebWith LAH, you reduce the nitro group as well, depending on the conditions, to the aryl hydroxylamine or aniline. I think, borane would do essentially the same. This is not a simple transformation. The reduction of nitro compounds are chemical reactions of wide interest in organic chemistry. The conversion can be effected by many reagents. The nitro group was one of the first functional groups to be reduced. Alkyl and aryl nitro compounds behave differently. Most useful is the reduction of aryl nitro … See more Reduction to anilines The reduction of nitroaromatics is conducted on an industrial scale. Many methods exist, such as: • Catalytic hydrogenation using: Raney nickel See more Reduction to hydrocarbons Hydrodenitration (replacement of a nitro group with hydrogen) is difficult to achieve but can be effected by catalytic hydrogenation over platinum on silica gel at high temperatures. The reaction can also be effected through … See more
WebNov 18, 2013 · I have been going through reduction of aldehydes using $\ce{LiAlH4}$ and $\ce{NaBH4}$. If there is a double bond conjugated with the carbonyl group, $\ce{LiAlH4}$ doesn't reduce it, leading to an allylic alcohol. However, using $\ce{NaBH4}$, some of the fully reduced alcohol will also be formed. Why is this so? WebJan 21, 2024 · The amine group is located by the position number. Groups that are attached to the nitrogen atom are located using “N” as the position number. More complex primary amines are named with —NH2 as the amino substituent. Can LiAlH4 reduce NO2 to NH2? Yes. Nitro groups are kind of weird.
