Answer to Question #142754 in Chemistry for Tiandra Cumberbatch

Question

a ketone will react with Tollens' reagent to produce a silver mirror, but an aldehyde will not is true or false

Answer 1

Solution:

FALSE.

Tollens’ test, also known as silver-mirror test, is a qualitative laboratory test used to distinguish between an aldehyde and a ketone. It exploits the fact that aldehydes are readily oxidized, whereas ketones are not.

Thus, an aldehyde will react with Tollens' reagent to produce a silver mirror, but a ketone will not.

Tollens’ reagent oxidizes an aldehyde into the corresponding carboxylic acid.

Example:

Answer: The statement "a ketone will react with Tollens' reagent to produce a silver mirror, but an aldehyde will not" is FALSE.
