Question
Write the product formed when benzaldehyde reacts with the following reagent:
Tollen’s reagent
Chemical Equations/Structures
Short Answer
Solution
\[\ce{C6H5CHO + 2[Ag(NH3)2] + 3OH- -> C6H5COO- + 2Ag_{(s)} + 2NH3 + 2H2O}\]
This reaction demonstrates the oxidizing power of Tollen's reagent and is a qualitative test for the presence of aldehydes. Benzaldehyde, being an aromatic aldehyde, gives a positive Tollen's test.
