Given The compound(s), which on reaction with HNO 3 will give the product having degree of rotation, [α] D = -52.7º is (are)

TestHub · Accepted Answer

Question Explanation:

D-Glucose on oxidation with HNO₃ gives a product P with a specific rotation of +52.7°. The question asks which compound(s) will give a product with [α]ᴰ = −52.7° on the same reaction.

Concept :

This question is based on Optical activity, Enantiomerism, Oxidation of sugars with HNO₃ . Solution:

Oxidation of an aldose like glucose with concentrated HNO₃ converts both the aldehyde (–CHO) and the primary alcohol (–CH₂OH) groups into carboxylic acids, forming an aldaric acid.

Hence, the oxidation product from carbohydrates in option 3 and 4 will show [α]ᴰ = −52.7°.
