(+) -

maltose,

L - (-) -

glucose and

L - (+) -

fructose in aqueous solution are

, respectively)

MARKS Content Team · Accepted Answer

Correct answer: (B) 'invert sugar' is an equimolar mixture of D-+ glucose and D--- fructose.; (C) specific rotation of 'invert sugar' is -20^o.. Invert sugar is an equimolar mixture of D-glucose and D-fructose, which is obtained by the hydrolysis of sucrose Specific rotation of mixture is the half of the sum of specific rotation of both components,(+52^o+-92^o)/2=-20^o (specific rotation +52°) +D-fructose (specific rotation -92°) Sucrose specific rotation +66° D-fructose →Br_2, H_2ONo reaction.

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)
