Aldohexoses have 4 chiral carbon atoms. Draw the Fischer projections of all the possible stereoisomers of aldohexose.
i. Provide the three possible stereoisomers of 2,3-difluoro-2,3-diiodobutane.
ii. Specify the enantiomers.
iii. Explain why one of the stereoisomers does not have an enantiomer.
Aldehydes are converted to primary alcohols when reacted with a reducing agent. Consider the two D-aldohexoses shown below: When both of them are reduced, one gives a chiral product and the other gives an achiral product. Explain.
Table sugar rotates plane-polarized light to the right. When it is hydrolyzed, a mixture called "invert sugar" forms which is made up of two types of simpler sugars of equal amounts (rotates plane-polarized light to the left). True or False: The simpler sugars must both rotate plane-polarized light to the left. Explain your answer.
Determine if the given Fischer projections are identical or enantiomers.
Indicate whether the Fischer projections shown below are identical or enantiomers.
Are the Fischer projections shown below identical or enantiomers?
