Tollens' reagent gives a silver mirror with:
AAcetone, the classic ketone solvent on the shelf
BMethanol, an alcohol on the chemist shop shelf
CAcetaldehyde, an aldehyde that reduces Ag$^+$ to Ag
DBenzene, an aromatic hydrocarbon on the bench too
Answer & Solution
Correct answer: C. Acetaldehyde, an aldehyde that reduces Ag$^+$ to Ag
Aldehydes reduce Tollens' Ag(NH$_3$)$_2^+$ to metallic silver (silver mirror). Acetone (ketone) does not.
