Preparation of carboxylic acids from acyl halides is a simple method in which the acid chloride or halide is hydrolysed to give carboxylic acids. The general reaction and examples are given below..
In case of carboxylic acids the negative charge is on the more electronegative element that is oxygen as shown in the structure in both of the resonating structures. The negative charge on the more electronegative element makes it more stable. And thus it shows acidic character easily. But in case of phenols the negative charge
