Which of the following pairs from the same osazone?

Options

  1. AGlucose and fructose
  2. BGlucose and galactose
  3. CGlucose and arabinose
  4. DLactose and maltose

Correct answer

A. Glucose and fructose

Step-by-step solution

All monosaccharides which differ in configuration at C 1 and C 2 gives the same osazone. Since, glucose and fructose differ from each other only in configuration at C 1 and C 2 therefore, they give the same osazone. All other options given in the questions do not satisfy this condition and hence, do not form the same osazone.
