WebNov 14, 2024 · Principle of Fehling’s test: The aldehyde group of sugar is oxidised by complexed copper ions to form acid. The red copper (I) oxide then precipitates, which is an indicator for the redox reaction. Formation of red precipitate of cuprous oxide is an evidence of the presence of reducing sugar. Reagents and materials required: WebFeb 7, 2016 · Thus, the C − H bond becomes stronger (the lesser the polarity of a bond, the stronger the bond ). So Fehling's solution (comparatively a weaker oxidizing agent than Tollen's reagent) can't oxidize benzaldehyde (an aromatic aldehyde). However, Fehling's solution can oxidize an aliphatic aldehyde.
