|
NH2OH
|
|
|
Conc. HNO3
|
|
|
(CH3CO)2O
|
|
|
NaHSO3
|
Explanation:
Detailed explanation-1: -Glucose does not answer Schiff’s test and NaHSO3 test due to absence of aliphatic aldehydes in the ring structure and absence of free aldehydic group.
Detailed explanation-2: -Glucose does not react with NaHSO3.
Detailed explanation-3: -Hence, acetophenone does not react with NaHSO3. Was this answer helpful?
Detailed explanation-4: -Nitrogenous compounds such as amino acids and proteins are frequently analyzed in tobacco since they are considered precursors of toxicants in cigarette smoke.
Detailed explanation-5: -Glucose does not react with 2, 4-DNP, Schiff’s reagent or NaHSO3. This is because the aldehyde group in glucose is involved in hemiacetal formation and thus is not free.
