For 'invert sugar', the correct statement(s) is (are)
(Given : specific rotations of (+) - sucrose, (+) - maltose, + `66^(@),+140^(@), -52^(@) and 92^(@)` respectively)

Options

A. Invert sugar' is prepared by acid catalyzed hydrolysed of maltose
B. Invert sugar' is an equimolar mixture of D-(+)-glucose and D-(-)-fructose
C. Specific rotation of 'invert sugar' is `-20^(@)`
D. On reaction with `Br_(2)` water, 'invert sugar' forms saccharic acid as one of the products

Answer

B, C

Explanation

`C_(12)H_(22)O_(11)+H_(2)O overset(H^(+))to underset(+52^(@))underset("D-(+)-glucose")(C_(6)H_(12)O_(6))+underset(-92^(@))underset("D-(-)-glucose")(C_(6)H_(12)O_(6))`
`alpha_("invert sugar")=(+52^(@)-92^(@))/2=-20^(@)` (average is taken as both monomers are one mole each)
