Question

When ammoniacal silver nitrate reacts with organic compounds, this test is called:

• A. Tollens' test
• B. Fehling's test
• C. Benedict's test
• D. Sanger's test

Hint:

Tollens' test is used to distinguish between aldehydes and ketones. Aldehydes react with Tollens' reagent to form a silver mirror.

Answer 1

The Correct Option is A

Tollens' test employs ammoniacal silver nitrate to detect aldehydes. This reagent reduces in the presence of an aldehyde group, precipitating a silver mirror onto the test tube's inner surface.
