What Gives Positive Fehling’s Test?
Hint: Aldehydes which are present in the sugar gives positive Fehling’s test. Fehling’s test is a chemical test which is generally used to distinguish between aldehydes and ketone functional groups

Fehling's test is used to distinguish between the presence of aldehydes and ketones in carbohydrates as ketone sugars except alpha-hydroxy-ketone do not react in this test. Fehling's test is performed in medical facilities to detect the presence of glucose in urine
Fehling's solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens' reagent test. The test was developed by German chemist Hermann von Fehling in 1849
