Explain the following:
Reaction of glucose that indicates that the carbonyl group is present as an aldehydic group in the open structure of glucose.

Explain the following : (i) Amino acids behave like salts rather than simple amines or carboxylic acids. (ii) The two strands of DNA are complementary to each other. (iii) Reaction of glucose that indicates the carbonyl group is present as an aldehydic group in the open structure of glucose.

Structure of the carbonyl group

The functional group present in aldehydes is -

How do you explain the absence of aldehyde group in the pentaacetate of D-glucose ?

The number of chiral centers in the open chain structure of glucose is :

Assertion: Glucose reacts with hydroxylamine to form an oxime and alsoadds a molecule of hydrogen cyanide to give cyanohydrin. Reason: The carbonyl group is present in the open chain structure of glucose.
