Answer 2

Answer:

(i) CH3COOH is not reduced by Feeling solution test.

Explanation:

Fehling solution is a test for -CHO group.

As we see, CH3COOH is the only group not containing CHO group hence doesn't give the test.

Note:Refer diagram as in (ii) part, there is a special condition. As you see, it has a CHO group hence gives Fehling solution test.
