      sir as OH is a good leaving group why can't it combine with H+ ion from h2So4, then oxygen from alcohol can form coordinate bond as C has positive charge. After that as Oxygen has positive charge it take electron from Hydrogen (-R'-O+-H). then H+ combines with HSo4 and h2so4 is returned as it is like catalyst. In this mechanism also oR' is coming from alcohol group. pleaseee respond @Physics Wallah - Alakh Pandey

    Without H2SO4 in esterification the reaction becomes reversible.It proceeds simultaneously with reversing. So what will be the mechanism then?

    sir as OH is a good leaving group why can't it combine with H+ ion from h2So4, then oxygen from alcohol can form coordinate bond as C has positive charge. After that as Oxygen has positive charge it take electron from Hydrogen (-R'-O+--H). then H+ combines with HSo4- and h2so4 is returned as it is like catalyst. In this mechanism also oR' is coming from alcohol group. pleaseee respond @Physics Wallah - Alakh Pandey
