Detailed explanation-1: -Answer and Explanation: Propene is converted into propanone in two steps, as described and shown below: Step 1: Acid-catalyzed hydration of the double bond in propene to produce 2-propanol. Step 2: Oxidation of 2-propanol by PCC (pyridinium chlorochromate) to produce propanone as the product.
Detailed explanation-2: -We can convert Propene to Propan-2-ol by reaction of the propene with acid. Propene reacts with acid in presence of water to produce Propan-2-ol. Step 3: In this step protonated alcohol reacts with the water molecule generating the product Propan-2-ol.
Detailed explanation-3: -Best Answer Propene when treated with hydrogen bromamide (HBr) in the presence of peroxide followed by addition of an aqueous solution of potassium hydroxide (KOH) gives propan-1-ol. Alternatively, propene can be directly treated with borane in the presence of tetrahydrofuran to given propan-1-ol.
Detailed explanation-4: -Step 1: Formation of Propan-2-ol. Propanone is treated with Lithium Aluminium hydride which acts as a reducing agent and reduces the ketone group to a alcohol. The product formed is Propan-2-ol. Step 2: Formation of Propene. The Propan-2-ol so formed now is treated with concentrated Sulphuric acid at .
