[PDF] alkene reaction with h2so4 and h2o

Alkenes react with concentrated sulfuric acid (H2SO4) at room temperature in a highly exothermic reaction. The electrophile is one of the hydrogen atoms in the acid molecule. If water is added after the reaction between sulphuric acid and ethene, the end product is an alcohol, and the sulphuric acid reforms.

  • What is the chemical reaction of H2SO4 H2O?

    When we add H2SO4 to H2O the H2SO4 will dissociate and break into H+ and SO4 2-. Since the H+ (often called a “proton”) and the SO4- are dissolved in water we can call them H+ (aq) and SO4- (aq).

  • What happens when you add H2O to an alkene?

    Hydration of Alkenes
    The net addition of water to alkenes is known as hydration. The result involves breaking the pi bond in the alkene and an OH bond in water and the formation of a C-H bond and a C-OH bond. The reaction is typically exothermic by 10 - 15 kcal/mol,1 but has an entropy change of -35 - -40 cal/mol K.
  • From alkenes (1) By acid catalysed hydration: Alkenes react with water in the presence of acid as catalyst to form alcohols. In case of unsymmetrical alkenes, the addition reaction takes place in accordance with Markovnikov's rule (Unit 13, Class XI). C=C3 + H,0 H, -ca H OH >.
