The product after oxidizing aldehyde
Webb4 sep. 2014 · It has been demonstrated that water adds rapidly to the carbonyl function of aldehydes and ketones to form geminal-diol. In a similar reaction alcohols add reversibly to aldehydes and ketones to form hemiacetals (h emi, Greek, half). This reaction can continue by adding another alcohol to form an acetal. Hemiacetals and acetals are important ... WebbFew examples of oxidizing agents for aldehyde include potassium permanganate and potassium dichromate in acid solution.
