a.
To explain:
Whether the carbohydrate D-mannose will produce a positive Benedict’s test or not.
Introduction:
On the basis of reactivity of carbohydrates, they can be classified as reducing and non-reducing sugars. The reducing sugars are those sugars in which free
b.
To explain:
Whether the carbohydrate L-fucose will produce a positive Benedict’s test or not.
Introduction:
On the basis of reactivity of carbohydrates, they can be classified as reducing and non-reducing sugars. The reducing sugars are those sugars in which free aldehyde or ketone group is present, which reacts with certain chemicals to reduce them. Non-reducing sugars lack free carbonyl group.
c.
To explain:
Whether the carbohydrate maltose will produce a positive Benedict’s test or not.
Introduction:
On the basis of reactivity of carbohydrates, they can be classified as reducing and non-reducing sugars. The reducing sugars are those sugars in which free aldehyde or ketone group is present, which reacts with certain chemicals to reduce them. Non-reducing sugars lack free carbonyl group.
d.
To explain:
Whether the carbohydrate glycogen will produce a positive Benedict’s test or not.
Introduction:
On the basis of reactivity of carbohydrates, they can be classified as reducing and non-reducing sugars. The reducing sugars are those sugars in which free aldehyde or ketone group is present, which reacts with certain chemicals to reduce them. Non-reducing sugars lack free carbonyl group.

- A. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry.
