Web8 apr. 2024 · Hydration: With the help of this process, water is added across double bonds of alkenes. As a result, it produces alcohol. Moreover, this reaction is catalysed by either sulphuric or phosphoric acid. Additionally, hydration is used in industries to produce synthetic ethanol. The equation here is, CH2=CH2 + H2O → CH3–CH2OH. WebWhile the addition of water to an alkene gives an alcohol, hydration of alkynes produces different products such as aldehydes and ketones. Since the rate of acid-catalyzed hydration of alkynes is much slower than alkenes, a mercuric salt like mercuric sulfate (HgSO 4 ) is usually added to facilitate the reaction.

The Stereochemistry of Alkene Addition Reactions

WebA representative example of a syn addition to alkenes would be the hydroboration-oxidation reaction where the H and OH groups are adding to the same side of the double bond. The reaction, however, is going with a different mechanism; there are no ionic intermediates and it is a concerted mechanism: Web24 sep. 2024 · Hydration is the process where water is added to an alkene to yield an alcohol.

"WebVideo transcript. In the last video, we saw how to add two OH groups on anti to each other. In this video, we'll see how to add them on the same side, or syn addition. So we start with our alkene and to our alkene, we add osmium tetroxide. So this is the OSO4 here. " - Hydration of alkene produces

10.6: Two Other Hydration Reactions of Alkenes

WebStep 1: First, a hydrogen atom (proton) is added to the alkene to give carbocation as an intermediate product. Two carbocations are formed in this reaction. According to the … WebFor the alkene that does not have a symmetric structure, the double bond carbons have different substituents so the question of which carbon gets the hydrogen is critical. For the example of the following reaction, two possible products could be produced: 2-bromo-2-methylpropane and 1-bromo-2-methylpropane. Which one is actually formed?
