Detailed Solution

D-glucose can be seen in three dimensions or using a Fischer projection. The cyclic monosaccharide -D-glucopyranose is created when the aldehyde group and the OH group on the fifth carbon atom combine.
Also D-molecular glucose's mass increases by 210 when treated with too much acetic anhydride.
But 2 doesn't explain 1.
