JEE AdvancedChemistryBiomoleculesMultiple correct+4 / −2
For "invert sugar", the correct statement(s) is(are) (Given : specific rotations of (+)-sucrose, (+)-maltose, L-(−-−)-glucose and L-(+)-fructose in aqueous solution are +66 ∘{}^\circ∘, +140 ∘{}^\circ∘, −-− 52 ∘{}^\circ∘ and +92 ∘{}^\circ∘, respectively.)
  1. A
    "invert sugar" is prepared by acid catalyzed hydrolysis of maltose.
  2. B
    "invert sugar" is an equimolar mixture of D-(+)-glucose and D-(−-−)-fructose.
