L es energ ch is supplied by the energy ation by ion-dipole interaction. Step 3. The carbocation formed is step 2 can either undergo nucleophilic attack by the bisulphate 10n UIl U Cart carboca (HSOg) or may eliminate a proton. Since HSOis a very weak nucleophile, therefore, nucleophilic substitunon reaction does not occur. Instead elimination of a proton occurs to form ethylene Fast LCH,CH, CH-CH, +H (Elimination) CH CH2 tOSO,H CH,CH-OSO H (Nucleophilic substitution) The whole process is reversible. In order to shift the equilibrium towards right, strong acids and high temperatures are used when the resulting alkene being more volatile than the starting alcohol escapes from the reaction mixture.

    HSO4- is weak nucleophile so nucleophilic substitution don't occur but here elimination can take place. nucleophilic substitution depends on concentration of reactant as well as nu...

    It is mentioned there shweta Hso4- is a weak nucleophile so nucleophilic substitution does not occur

    why it is weak
  • Suman Kumar thankyou
    HSO4 - is a very poor nucleophile so it can't attack the carbocation instead it will abstract the proton
