  • What is the mechanism of acid catalysed hydrolysis?

    Acid-catalyzed hydrolysis of ester is reversible and occurs by SN1 pathway. Acid catalysts speed up the reaction by protonating carbonyl oxygen and thus rendering carbonyl carbon more susceptible to nucleophilic attack.

  • What is the mechanism of sucrose hydrolysis?

    In molecular terms, hydrolysis of sucrose involves (a) breaking of a covalent bond in sucrose and hence formation of fructose and glucose, (b) a change in the number of hydrogen bonds between fructose and H2O and between glucose and H2O, and (c) a change in the hydrogen bond equilibrium between H2O and HCl and between

  • What is the acid hydrolysis of sucrose method?

    Thus, the acidic hydrolysis of sucrose is carried out in the acidic medium such as hydrochloric acid. The products formed are glucose and fructose. During the whole process of hydrolysis, the dextrorotatory sucrose leads to the formation of laevorotatory products.
  • Acid catalyzed hydration of alkenes involves replacing the pi bond on an alkene with a water molecule. This is done by adding an alcohol to the more substituted carbon atom, and hydrogen to the less substituted carbon atom. This reaction follows Markovnikov's rule and may undergo a carbocation rearrangement.
