I had a doubt while reading about the saponification reaction of esters in basic medium. What is the molecularity of the reaction and why?
P.S - I think its bimolecular and heres why -
The RDS of the reaction is the formation of the tetrahedral intermediate after the attack of the OH ion. In this step both the ester and the hydroxide ion are involved (The ester is shifting the carbonyl bond electrons to the oxygen and the hydroxide is attacking the electrophilic carbon). Therefore, the molecularity should be two.
