    correct but some corrections 1. positive charge on O 2. It is SO3 not SO3H. So3 is the electrophilic

    Yes mechanism is correct...little bit correction required. Last you can do protonation leads to sulohonic acid product. In all your previous mechanism you did one common mistake that after the donation of lone pair from oxygen there is positive charge over oxygen

    sir electrophile so3h Lena ya so3

    eduncle-logo-app

    SO3 electrophile hai

    eduncle-logo-app

    overall positive charge sulphur pe concentrate rehte hai...so ye electrophile hote hai or electrophilic substitution reaction dete hai but isme oxygen pe jo negative charge hote hai wo so3- ke according dikhte hai

    eduncle-logo-app

    last me protonation hote hai to H+ add hote hai leads to sulohonic acid product
