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^(o+))hArr RCOOR'+H_(2)O`
Which of the following is 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.
