Hexanone: ketone
Hexanal: aldehyde
Hexanol: alcohol
What type of bond will be made? What disaccharide is formed from these two monosaccharides?
beta 1,4 - glycosidic bond will be made. Lactose is formed.
A sample of oxygen at room temperature occupies a volume of 250. L at 1.50 atm. What would be the volume of this gas at 7.50 atm at the same temperature?
50L
What type of bond is formed and what are we making? Is it a monosaccharide, disaccharide, or polysaccharide?
It is an alpha-1,4-glycosidic bond. We are making beta-maltose, a disaccharide.
Using this equation:
NO + O2 --> NO2 (is it balanced?)
If we have 0.765 moles of NO, how many grams of NO do we have? Using that number of grams, determine how many grams of NO2 we will have as well.
2NO + O2 --> 2NO2
22.96 g NO
35.20g NO2
Draw and name:
a molecule containing an ether
a molecule containing a thiol
Check for correct answer
This is D-glucose. From D-glucose, draw D-galactose. (hint, the only difference is on carbon 4). Oxidize D-galactose, showing it's structure. Reduce D-galactose, showing it's structure.
D-galactose:
When oxidized, aldehyde goes to a carboxylic acid. When reduced, aldehyde goes to an alcohol
