An explanation corresponding to the given statement that if gentiobiose is a reducing sugar and whether it shows mutarotation is to be stated. Concept introduction: Gentiobiose is a naturally occurring carbohydrate. It is composed of two glucose units which are joined by a β − 1 , 6 glucosidic linkage. Tollens test is a laboratory test which is used to identify an aldehyde and a ketone . It is also known as silver mirror test. In this test, oxidation of aldehyde takes place, whereas ketone does not give this test. Thus, the reaction of aldehyde with Tollens reagent gives a positive Tollens test.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation Introduction

Interpretation: An explanation corresponding to the given statement that if gentiobiose is a reducing sugar and whether it shows mutarotation is to be stated.

Concept introduction: Gentiobiose is a naturally occurring carbohydrate. It is composed of two glucose units which are joined by a β−1,6 glucosidic linkage.

Tollens test is a laboratory test which is used to identify an aldehyde and a ketone. It is also known as silver mirror test. In this test, oxidation of aldehyde takes place, whereas ketone does not give this test. Thus, the reaction of aldehyde with Tollens reagent gives a positive Tollens test.
