When sugar 'XX' is boiled with dilute H2SO4{H}_{2}{SO}_{4} in alcoholic solution, two isomers 'AA' and 'BB' are formed. 'AA' on oxidation with HNO3{HNO}_{3} yields saccharic acid where as 'BB' is laevorotatory. The compound 'XX' isWhen sugar ' X ' is boiled with dilute H _ 2 SO _ 4 in alcoholic solution, two isomers ' A ' and ' B ' are formed. ' A

Options

  1. AMaltose
  2. BSucrose
  3. CLactose
  4. DStrach

Correct answer

B. Sucrose

Step-by-step solution

When sugar ' X ' is boiled with dilute H _ 2 SO _ 4 in alcoholic solution, two isomers ' A ' and ' B ' are formed. ' A

Compound X is Sucrose. which on acidic hydrolysis gives Glucose and fructose.

Glucose on oxidation with HNO3{HNO}_{3} yields saccharic acid where as fructose is laevorotatory.
