Which of the following compound(s) does not react with Fehling solution?
(A) $CH_3CHO$
(B) $Ph-CHO$
(C) Glucose
(D)
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (B) and (D) only
Fehling’s solution is reduced by aliphatic aldehydes and reducing sugars, but not by aromatic aldehydes or ketones.
Now check each compound:
- (A) CH₃CHO (ethanal) → aliphatic aldehyde reacts
- (B) Ph–CHO (benzaldehyde) → aromatic aldehyde does not react
- (C) Glucose → reducing sugar reacts
- (D) (shown structure is acetone, a ketone) does not react
Compounds that do not react with Fehling’s solution: (B) and (D)
