, , and and 'invert sugar' is prepared by acid catalyzed hydrolysis of maltose

, will result in -2 marks, as a wrong option is also darkened. 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) 'invert sugar' is an equimolar mixture of D-(+)-glucose and D-(-)-fructose

and and specific rotation of 'invert sugar' is -20°

. ONE OR MORE THAN ONE of these four option(s) is(are) correct. • For each question, marks will be awarded in one of the following categories: Full Marks : +4 If only the bubble(s) corresponding to all the correct option(s) is (are) darkened Partial Marks : +1 For darkening a bubble corresponding to each correct option, provided NO incorrect option is darkened. Zero Marks : 0 If none of the bubbles is darkened Negative Marks : -2 In all other cases • For example, if are all the correct options for a question, darkening all these three will result in +4 marks; darkening only will result in +2 marks; and darkening on reaction with Br 2 water, 'invert sugar' forms saccharic acid as one of the products
