Carboxylic acid, although unreactive to alcohols, reacts in the presence of small amount of `conc. H_2 SO_4` or with `2-3 %` of `HCl` ?
`RCOOH + R'OH overset (H^(oplus)) hArr RCOOR' + H_2 O`
Which of the following statements is//are correct about the above reaction ?
(I) This reaction is called Fischer esterification reaction.
(II) The equilibrium is shifted to `R.H.S` if `H_2 O` is removed by azeotropic distillation with benzene.
(III) The reaction of `RCOCl` and `R'OH` to give ester `(RCOOR')` is irreversible and more feasible than esterification of `RCOOH`.
(IV) If the above esterification of `RCOOH` is carried out in excess of `R'OH`, the equilibrium is shifted to `R.H.S`.
