MCQ
Sugar which does not give reddish brown precipitate with Fehling's reagent is:
- ✓Sucrose
- BLactose
- CGlucose
- DMaltose
✓
Answer
Correct option: A.
Sucrose
a
Sucrose do not contain hemiacetal group.
Sucrose do not contain hemiacetal group.
Hence it does not give test with Fehling solution.
While all other give positive test with Fehling solut
