Question

1,2-дибромциклогексан+ 2KOH(спиртовый)=(t)=? циклогексен=(KMnO4, [H2SO4])=? что будет в результате реакции? (то, что в скобках - это над стрелочкой в уравнениях)

Answer 1

В первой реакции образуется 1,2-дигидроксициклогексан, а во второй циклогексен окислится до гександиовой кислоты

Answer 2

Reaction 1: 1,2-Dibromocyclohexane + 2KOH (alcoholic) = ?

The reaction between 1,2-dibromocyclohexane and 2KOH (alcoholic) can result in the formation of cyclohexene. The alcoholic KOH acts as a base and abstracts a proton from the 1,2-dibromocyclohexane molecule, leading to the elimination of two bromine atoms and the formation of a double bond in the cyclohexene molecule.

Reaction 2: Cyclohexene + KMnO4 + H2SO4 = ?

The reaction between cyclohexene, KMnO4, and H2SO4 is an oxidation reaction. In this reaction, cyclohexene is oxidized by potassium permanganate (KMnO4) in the presence of sulfuric acid (H2SO4). The double bond in cyclohexene is broken, and the carbon atoms are oxidized to form a diol (a compound with two hydroxyl groups). The purple color of KMnO4 is reduced to a colorless solution.

Result of the Reactions:

The overall result of the two reactions can be summarized as follows: 1,2-Dibromocyclohexane + 2KOH (alcoholic) → Cyclohexene Cyclohexene + KMnO4 + H2SO4 → Diol
