Q19 / 90 · JEE Main 2022 (28 Jun Shift 2) · Chemistry

When sugar 'X' is boiled with dilute H2SO4 in alcoholic solution, two isomers 'A' and 'B' are formed. 'A' on oxidation with HNO3 yields saccharic acid where as 'B' is laevorotatory. The compound 'X' is

  • A
    Maltose
  • Correct answer
    B
    Sucrose
  • C
    Lactose
  • D
    Strach

Solution

Figure

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

Glucose on oxidation with HNO3 yields saccharic acid where as fructose is laevorotatory.

Hence, the correct answer is option: 'B'.
