Vedclass · Answer

(C) $FeCl_3$ is used to detect phenols by forming a violet-colored complex. Fehling solution is used to detect reducing sugars like glucose. $NaHSO_3$ (sodium bisulfite) is used to detect carbonyl compounds (aldehydes and ketones) by forming a crystalline addition product. Tollen’s reagent is used to detect aldehydes,not unsaturation. Unsaturation is typically detected using bromine water or Baeyer's reagent. Therefore,the statement that Tollen’s reagent is used in the detection of unsaturation is incorrect.
