Answer»

By acidic hydrolysis $- C N$ group changes to $- C O O H$ given

I. $C H_{3} - C H | C N - C H O H_{3} O^{+} - --- \to C H_{3} - C H | C O O H - C H O$

II. $C H_{3} - C H | O H - C N H_{3} O^{+} - --- \to C H_{3} - C H | O H - C O O H$

III. $C H_{3} - O | | C - C N H_{3} O^{+} - --- \to C H_{3} - O | | C - C O O H$

In which case(s) preference of nomenclature changes?
