Polyhydric alcohols react with copper(II) hydroxide at room temperature. Add freshly prepared to the test tube. Both aldehydes and glucose (which contains an aldehyde
Both aldehydes and glucose (which contains an aldehyde group) react with upon heating. Add and heat the mixture gently. Glycerol) The blue precipitate dissolves
Below is a structured report (essay-style) for this practical work. 1. Define the Objective
✅ Through the systematic application of qualitative reagents, we successfully identified the organic compounds. The experiment demonstrates that the chemical properties of functional groups allow for the precise differentiation of substances within different homologous series.
