The name and structure of the alditol formed by reduction of NaBH 4 D-fructose other than the D-sorbitol should be determined. Concept Introduction: The sodium borohydride is a reducing agent, so it reduces the functional group present in the carbohydrate and itself get oxidized. The reduction of aldehyde results in the formation of alcohol because reduction can also be defined as addition of hydrogen atom thus, -CHO group becomes -CH 2 OH after addition of two hydrogen atoms on carbonyl carbon of the aldehydic group.

Question

Which statements are correct regarding the formation of maltose?A. Hydrolysis reaction between alpha-D-glucose and beta-D-glucoseB. Condensation reaction between alpha-D-glucose and beta-D-glucoseC. Condensation reaction between beta-galactose and beta-glucoseD. Hydrolysis of starch into a di-saccharide product a). A and B b). C and D c). B and D d). B and C e). B, C and D

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.

Concept Introduction:

The sodium borohydride is a reducing agent, so it reduces the functional group present in the carbohydrate and itself get oxidized.

The reduction of aldehyde results in the formation of alcohol because reduction can also be defined as addition of hydrogen atom thus, -CHO group becomes -CH₂ OH after addition of two hydrogen atoms on carbonyl carbon of the aldehydic group.
