AIIMS 2019 Chemistry Oxidation Reactions MCQ Question
Assertion : Glyceraldehyde reacts with 2 2 Br /H Oto form achiral compound
Reason: –CHO and both are oxidized
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option C is correct because the reaction of glyceraldehyde with Br₂/H₂O leads to the formation of a carboxylic acid, specifically glyceric acid, through the oxidation of the aldehyde group. Br₂/H₂O acts as an oxidizing agent, facilitating the conversion of the aldehyde (-CHO) to a carboxylic acid (-COOH) by adding an oxygen atom and removing two hydrogen atoms.
Option A is misleading as it implies that glucose is the only substrate affected by Br₂/H₂O, while the question specifically addresses glyceraldehyde. Since options B and D are not provided, they cannot be evaluated for correctness.
