Question

The presence of Carbonyl group in glucose is confirmed by its reaction with hydroxylamine. Identify the type of carbonyl group present and its position. Give a chemical reaction in support of your answer.

Answer 1

The carbonyl group present in glucose is aldehyde and the \(C_1\)atom . Glucose gets oxidised to six-carbon carboxylic acid (gluconic acid) with COOH group at the \(C_1\) atom on reaction with a mild oxidising agent like bromine water. This indicates that the carbonyl group is present as an aldehydic group.
