All monosaccharides ____ Tollens' reagent.
1 oxidise
2 condense with
3 reduce
4 add to
Explanation:
Due to presence of \( - {\rm{CHO}}\) group all monosaccharides and disaccharides except sucrose reduce Tollens' reagent to shining silver mirror.

1 0.75
2 1.5
3 3
4 4.5
Explanation:

What does ' \(\mathrm{\mathrm{D}}\) ' and \(\mathrm{(+)}\) signifies in \(\mathrm{\mathrm{D}-(+)-}\) glucose?
1 D represents conformation and \(\mathrm{(+)}\) represents the laevorotatory nature of molecule
2 D represents configuration and \(\mathrm{(+)}\) represents the dextrorotatory nature of molecule
3 D represents conformation and \(\mathrm{(+)}\) represents the dextrorotatory nature of molecule.
4 D represents configuration and \(\mathrm{(+)}\) represents th laevorotatory nature of molecule.
Explanation:
Glucose is correctly named as \(\mathrm{\mathrm{D}(+)}\) glucose. \(\mathrm{\mathrm{D}}\) before the name of glucose represents the configuration whereas ' \(\mathrm{(+)}\) ' represents dextrorotatory nature of the molecule. [It may be remembered that ' \(\mathrm{\mathrm{D}}\) ' and '\(\mathrm{\mathrm{L}}\)' have no relation with an optical activity of the compound].
