  • Nucleophilic order

    HO- vs CH3O- ?
    And reason



  • @kirito

    first thing it is because of experiment.

    It can be explained by the theory of conjugate base. Reactions are CH3OH giving CH3O[-] + H[+]

    H2O giving HO[-] + H[+] . Conjugate acids are CH3OH and H2O. Pka values for CH3OH and H2O are 15.5 and 15.7. So CH3OH is strong acid than H2O. Conjugate base CH3O- is less basic. So OH- is stronger nucleophile than CH3O-"

    but normally RO- is more than OH-
