The correct statement(s) regarding sugars is(are):Given: Specific rotations of L–(−)–glucose and L–(+)–fructose are \( -52.5^\circ \) and \( +92.5^\circ \), respectively.
On treatment with \( \mathrm{HNO_3} \), gluconic acid is oxidized to saccharic acid, whereas glucose is not oxidized to saccharic acid.
Fructose gives a positive Fehling's test because it isomerises to glucose and another aldohexose in the presence of Fehling's reagent.
Invert sugar is an equimolar mixture of D-glucose and D-fructose formed after hydrolysis of the corresponding disaccharide.
Specific rotation of invert sugar is \( -40^\circ \).
