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

Options

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

Correct answer

B. Sucrose

Step-by-step solution

Compound X is Sucrose. which on acidic hydrolysis gives Glucose and fructose. Glucose on oxidation with HNO 3 yields saccharic acid where as fructose is laevorotatory.
