STRUCTURE OF GLUCOSE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Glucose adds a molecule of ____ to form cyanohydrin
A
NH3
B
HCl
C
HCN
D
CO
Explanation: 

Detailed explanation-1: -When glucose reacts with hydroxylamine, oxime is formed and cyanohydrins are formed on the addition of hydrogen cyanide to it. This reaction can confirm the presence of carbonyl group in glucose.

Detailed explanation-2: -Glucose does not react with HCN.

Detailed explanation-3: -HCN is produced commercially by the reaction of ammonia, methane, and air over a platinum catalyst or from the reaction of ammonia and methane. HCN is also obtained as a by-product in the manufacture of acrylonitrile and may be generated during many other manufacturing processes (Pesce 1994).

Detailed explanation-4: -NH 2 OH . Glucose reacts with hydroxylamine to form an molecule and adds a molecule of hydrogen cyanide to give cyanohydrin. These reactions confirm the presence of a carbonyl group in glucose. The D(+)-glucose contains aldehyde groups in its structure.

Detailed explanation-5: -D(+)-glucose reacts with hydroxyl amine and yields an oxime. The structure of the oxime would be. No worries! We’ve got your back.
