D-tagatose is a 2-ketohexose which forms same osazone as D-galactose. What is the structure of D-tagatose

Monosaccharides have -CHO (or C=O) and -OH groups, so they undergo usual oxidation and reduction. Further, monosaccharides from osazone when treated with excess of phenylhdrazine (3 equivalents). In osazone formation only the first two carbon atoms are involved. Thus monosaccharidxes having identical configuration on reset of C atoms except first two will form same osazone, as is the case with glucose and fructose. A, B and C are three hexoses and form same osazone D. Compounds A to D behave as below (A) D overset(HCl)rarr underset(CH_(3)COOH)overset(Zn)rarr D - Fructose (B) A overset(Ni.H_(2))rarr overset(HNO_(3))rarr underset(H_(3)O^(+))overset(Na-Hg)rarr B + C (C ) B overset(HNO_(3))rarr Optically active glycaric acid (D) C overset(HNO_(3))rarr Optically inactive glycaric acid Compound D is an osazone which can be obtained from

Monosaccharides and disaccharides in which aldehyde group is free reduce Tollen's reagent as well as Fehling solution and hence are known as reducing sugars. Carbohydrates react with excess of phcayl kydrazine to yield their crystalline derivatives called oxazones.
