All of the statements concerning monosaccharides are correct except
A) the number of stereoisomers possible is 2n,where n is the number of chiral carbon atoms in the molecule.
B) monosaccharides with 5 or 6 carbon atoms exist in solution in cyclic form.
C) the two different cyclic forms of a particular monosaccharide are called tautomers.
D) a molecule is classified as a d or l isomer by the position of the hydroxyl group on the chiral center farthest from the carbonyl group.
E) monosaccharides have the general formula Cn(H2O) n,but this only describes the number and kinds of atoms,not their structure.
