D-mannose when subjected to Wohl degradation followed by Br₂/H₂O produces the same aldonic acid as does______ when treated with Br₂/H₂O.

Question

Quizplus · Accepted Answer

Wohl degradation followed by Br₂/H₂O is a method to convert an aldose sugar into its corresponding aldonic acid. When D-mannose undergoes this reaction, it forms D-mannonic acid. The same product is obtained when D-arabinose is subjected to this reaction. Therefore, the correct choice is A) D-arabinose. The other sugar choices (D-ribose, D-xylose, D-lyxose, and D-threose) will produce different aldonic acids.
