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°, +140°, –52° and +92°, respectively).
(Given : specific rotations of (+)-sucrose, (+)-maltose, L-(–)-glucose and L-(+)-fructose in aqueous solution are +66°, +140°, –52° and +92°, respectively).
- ‘invert sugar’ is prepared by acid catalyzed hydrolysis of maltose
- ‘invert sugar’ is an equimolar mixture of D-(+)-glucose and D-(–)-fructose
- specific rotation of ‘invert sugar’ is –20°
- on reaction with Br2 water, ‘invert sugar’ forms saccharic acid as one of the products.
Answer
(C) specific rotation of ‘invert sugar’ is –20°
