1.	For 'invert sugar', the total number of 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) (I) ‘invert sugar’ is prepared by acid catalyzed hydrolysis of maltose. (II) ‘invert sugar’ is an equimolar mixture of D-(+)~giucose and D-(-)-fruetose. (III) specific rotation of‘invert sugar’ is -20°. (IV) on reaction with Br_2 water, ‘invert sugar’ forms saccharic acid as one of the products.
Answer» Solution :(2) Invert sugar is an equimolar mixture of D-(+) glucose and D(-) glucose. `underset(+"sucrose")(C_(12)H_(22)O_(11)) + H_(2)O overset(H^(+)) to underset("invert sugar")(C_(6)H_(12)O_(6) + O_(2) overset(+)to C_(6)H_(12)O_(6))` Specific rotation of invert sugar = `(-92^(@)+52^(@))/2 = -20^(@)` D-glucose on oxidation with `Br_(2-)` WATER produces gluconic ACID and not saccharic acid.
