# What reaction is the opposite of esterification?

Jul 9, 2018

$\text{Is this not saponification...?}$

#### Explanation:

For $\text{esterification}$ we would write...

$R C {O}_{2} H + H O R ' \stackrel{{H}_{3} {O}^{+} , \Delta}{\rightarrow} R C {O}_{2} R ' + {H}_{2} O$

And for $\text{saponification}$ we would write...

$R C {O}_{2} R ' \stackrel{H {O}^{-} , \Delta}{\rightarrow} R C {O}_{2}^{-} + H O R '$

The reaction may be performed under acidic or basic conditions...
