A) \[\alpha -D(+)-\]glucose undergoes mutarotation
B) It has four asymmetric carbons is Fischer projection formula
C) It gives saccharic acid with Tollens reagent
D) It reacts with hydroxyl amine
Correct Answer: C
Solution :
Glucose reduces Tollens reagent and gets oxidised into gluconic acid. \[\underset{C{{H}_{2}}OH}{\overset{CHO}{\mathop{\underset{|}{\overset{|}{\mathop{(CHOH)}}}\,}}}\,+A{{g}_{2}}O\xrightarrow{{}}\underset{\begin{smallmatrix} C{{H}_{2}}OH \\ gluconic\,acid \end{smallmatrix}}{\overset{COOH}{\mathop{\underset{|}{\overset{|}{\mathop{{{(CHOH)}_{4}}}}}\,}}}\,+\underset{\begin{smallmatrix} \text{silver} \\ \text{mirror} \end{smallmatrix}}{\mathop{2Ag}}\,\]
