Question

Fehling's solution gives a brick-red precipitate with:
  1. A
    Glucose and aliphatic aldehydes (not aromatic)
    Correct
  2. B
    All aldehydes
  3. C
    Ketones only
  4. D
    Carboxylic acids

Correct answer

Glucose and aliphatic aldehydes (not aromatic)

Explanation

Fehling's solution (Cu²⁺ in alkaline tartrate) is reduced by aliphatic aldehydes and sugars to Cu₂O (brick-red precipitate). Aromatic aldehydes (benzaldehyde) and ketones do NOT reduce Fehling's.
